If we ignore such "micro optimizations", we will quickly bloat Emacs,
since those small amounts add up.  We have a lot of relatively small
potential additions that we make a point of not adding, because if we
decide adding one is okay, then why not add all the rest?  We don't
add such stuff to subr.el or to simple.el or to files.el, and keep
them separate, precisely because adding them all will not be
insignificant.

The only way of keeping this kind of bloat at bay is to resist adding
anything, no matter how small, because, like I said, it's a slippery
slope.

I don't see the relevance, sorry.  We can work on making Emacs faster
without bloating it.
