IMHO this warning must not mean that much.

AFAIU it's always switched on, if the state was
changed. That doesn't mean present state must differ
from state as variable was set.

Think at the result of

(buffer-modified-p)

If you open a file, it says nil, not modified.

If you insert a char and delete it afterwards, buffer
contents is as opened, however considered modified by
(buffer-modified-p).

`transient-mark-mode' AFAIK might have been set on and
off by several functions during execution, usually
restoring the state before, however that depends from
the functions called.

So set it to your need and forget the warning unless
more indications counsel otherwise.
