I don't think that we need to clarify the pitched_alloc_device API entry point, because it is guaranteed to return the right thing for a user.
What we should clarify is a case described below, where user does not wish to use the pitched_alloc_device, but instead another USM allocation function which on its own may not follow any requirements for images.
I would maybe suggest renaming the section into "Alignment restrictions and queries" to generalize it and add a paragraph (either at the beginning, or at the end) saying that base USM pointer that use used as a storage for an image may have additional backend-specific requirements for the alignment. For example, for OpenCL and Level Zero backend the base USM pointer that is used as an image storage must be aligned to a pixel size.
