These functions you are patching are not in performance-sensitive code,
so I doubt this makes any difference performance wise. I doubt
Microsoft will ever remove these deprecated functions, given its history
of backwards compatibility, so from that perspective this change does
not achieve anything either.
If users don't adapt to the new API, the old one will never really expire.
If you were proposing to change how palloc() allocates memory, that
would be quite different and perhaps useful, as long as a benchmark
accompanies the patch.
This is irrelevant to the discussion.
Neither the patch nor the thread deals with palloc.
