On a desktop system, it is not unusual for /usr usage to vary, as you
install, and maybe remove, various packages as your needs change.

As for not making it large enough to begin with, isn't one of the
advantages of using LVM that you don't need to try to guess future usage
and only need to make the LV large enough for today's needs. That's one
of the main reasons I used LVM, before The One True Way[tm] was available
on Linux.

Keep on using LVM if it is right for you, and it apparently is, but you
will have to compromise on using an initramfs to do so reliably in the
future.

I seriously recommend you look at the Wiki page on making your own
initramfs. One of the problems people have with them, and I was one of
them, is that they are a black box, a binary blob that does some magic to
get your system booted. Playing around with creating your own shows you
just how simple and basic they really are, a busybox binary and a couple
of lines of shell script to mount / and /usr. If you fear the unknown,
get to know it.
