No objection from me.

Consistency can help in general, but it's not an
imperative.  More important than global consistency
is local consistency (e.g. within Isearch, don't use
more than one way to name the same thing).

It's probably too late to change `zap-to-char', but
I think that `through' is clearer than `to', when
the char is included.  `zap-through-char' would be
clearer, and it's confusing to have both `-to-' and
`-up-to-'.

(There currently is no Isearch yank command that has
"through" semantics, but I added a couple in my code
and in the patch I submitted for bug #37417.)
