That's even more vague - not a clarification at all.
What is the behavior change?  What kind of adaptation
are you hinting at?

Let's not quibble over the word "replace", please.

You imply that "the behavior of 'x-show-tip'" will
change.  That's what I'm asking about, in talking
about "replacement".

You also said that we should not use 'x-show-tip'
but should use only `tooltip-show', which is much
more limited - not a substitute for 'x-show-tip'
at all.

The question is, if `x-tool-tip' is not expected
to be replaced, but it is expected to change, just
_how_ is it expected to change?

Will we be able to do with the "new" `x-show-tip',
what we can do with it now, even if we must "adapt"
in some way to be able to do that?

You are being quite vague, it seems.  You make a
pronouncement that we should not use the function,
but also that it will change - somehow.

The real question is not the words to name the
impending change or replacement that you warn us
about.

The question is how, after the change/replacement,
to get done everything we can do now with that
function.
