Yes.

libtool allows you to exploit the versioning capabilities of the runtime
linkers on different systems. Not all the world is a GNU/Linux box, and
some non-glibc runtime linkers have different versioning semantics.

*You* the developer that uses libtool shouldn't ever need to use
subtraction. libtool does that for you.

Yes, you are wrong. You are simply doing non-GNU/Linux users a
disservice, by effectively disabling library versioning capabilities for
them. I'm not sure how to best explain that to you.
