You can combine these two methods by specifying non-zero maxGpu* as well as maxCpu* parameters. The library automatically chooses best method to defragment each memory pool.
You may try not to block your entire program to wait until defragmentation finishes, but do it in the background, as long as you carefully fullfill requirements described in function vmaDefragmentationBegin().

When using lost allocations, you may see some Vulkan validation layer warnings about overlapping regions of memory bound to different kinds of buffers and images. This is still valid as long as you implement proper handling of lost allocations (like in the example above) and don't use them.
You can create an allocation that is already in lost state from the beginning using function vmaCreateLostAllocation(). It may be useful if you need a "dummy" allocation that is not null.
You can call function vmaMakePoolAllocationsLost() to set all eligible allocations in a specified custom pool to lost state. Allocations that have been "touched" in current frame or VmaPoolCreateInfo::frameInUseCount frames back cannot become lost.

There are some exceptions though, when you should consider mapping memory only for a short period of time:
- When operating system is Windows 7 or 8.x (Windows 10 is not affected because it uses WDDM2), device is discrete AMD GPU, and memory type is the special 256 MiB pool of
DEVICE_LOCAL + HOST_VISIBLE memory (selected when you use VMA_MEMORY_USAGE_CPU_TO_GPU), then whenever a memory block allocated from this memory type stays mapped for the time of any call to vkQueueSubmit() or vkQueuePresentKHR(), this block is migrated by WDDM to system RAM, which degrades performance. It doesn't matter if that particular memory block is actually used by the command buffer being submitted.

You can even use VMA_ALLOCATION_CREATE_MAPPED_BIT flag while creating allocations that are not necessarily HOST_VISIBLE (e.g. using VMA_MEMORY_USAGE_GPU_ONLY). If the allocation ends up in memory type that is HOST_VISIBLE, it will be persistently mapped and you can use it directly. If not, the flag is just ignored. Example:

General purpose memory allocation.
Remember that using resources that alias in memory requires proper synchronization. You need to issue a memory barrier to make sure commands that use img1 and img2 don't overlap on GPU timeline. You also need to treat a resource after aliasing as uninitialized - containing garbage data. For example, if you use img1 and then want to use img2, you need to issue an image memory barrier for img2 with oldLayout = VK_IMAGE_LAYOUT_UNDEFINED.

Alignments of different allocations made from one block may vary. However, if all alignments and sizes are always multiply of some size e.g. 4 B or sizeof(MyDataStruct), you can express all sizes, alignments, and offsets in multiples of that size instead of individual bytes. It might be more convenient, but you need to make sure to use this new unit consistently in all the places:

That is all. The extension will be automatically used whenever you create a buffer using vmaCreateBuffer() or image using vmaCreateImage().
When using the extension together with Vulkan Validation Layer, you will receive warnings like this:
vkBindBufferMemory(): Binding memory to buffer 0x33 but vkGetBufferMemoryRequirements() has not been called on that buffer.
It is OK, you should just ignore it. It happens because you use function vkGetBufferMemoryRequirements2KHR() instead of standard vkGetBufferMemoryRequirements(), while the validation layer seems to be unaware of it.
