Without t-m-m, the region can not become active.

That doesn't explain why I would disable t-m-m.

Perhaps there is a way to disable the highlighting.  I haven't found out
how something is highlighted.

I've never had an issue with the region deactivating itself randomly.
Under what circumstances exactly does this happen?

Are you referring to commands deactivating the region?  That could be
configurable, though I'm not sure how useful it is to indefinitely do
something with a region until it is explicitly deactivated.  What do you
plan on doing with it that would require this?

Highlighting the region all the time is probably not very useful.

Disabling t-m-m doesn't make any sense at all.  Why would anyone disable
it?

I can see it for someone who doesn't like the highlighting, so if it was
configurable --- and it is amazing that is isn't --- whether to
highlight the region when it's active or not, everyone who dislikes the
highlighting could have t-m-m enabled.  I would remove having it
disabled entirely from Emacs because there is no point in that and only
complication.

Without highlighting, a different indicator could be useful to show
whether the region is active or not, like a hint in the mode line.
