we had something like this (and also FS size) in our TODO for years.
So, I don't see problem to add it now. Send patch ;-)
All you need is to add
libblkid/src/superblocks/superblocks.c: blkid_probe_set_fs_blocksize()
to add "BLKSZ" variable to the probing result (use for example
blkid_probe_set_version() as a template).
And then use this function in FS specific probers. The variable will
automatically visible for udev as ID_FS_BLKSZ=.
