The current heuristic about translation-table-for-input is
We translate a character to what matches
buffer-file-coding-system of a buffer to which a user is
going to insert that character.
But you are going to extend that heuristic to:
We translate a character event to what matches
buffer-file-coding-system of the current buffer
(regardless of how the character is going to be used).
I basically agree that such an extension is good considering
the current limitation of non-unicode Emacs. But, as we are
in the stage of feature freeze, I think we should not do
that unless there's no other way to fix a problem.
And, for the current case, we do have another solution;

With your change, what (read-char) returns will be different
depending on buffer-file-coding-system. I don't know a
single actual example, but one may bind a non-ASCII
character to some command, or one may have his own input
method that does something about typed non-ASCII character.
Your change may break such cases.

I don't oppose to that.

At least the current statement is clear that it should not
be used for translating in read-char.
Char table for translating self-inserting characters.
This is applied to the result of input methods, not their input. See also
Anyway, as far as I know, we are now discussing "what its
job should be".
We (me and Stefan) has already shown opinions and solutions
to the problem. Richard, could you please decide what to
