ACBL is very conservative about changes to the alert procedures. Until
sometime in the 90's transfers were alerted, as were NT ranges that
extended out of the 15-18 range. The problem was that transfers had
become so common that when anyone alerted these bids, the opponents
didn't bother to ask, they just assumed it was Jacoby. If someone were
playing something else, the opponents wouldn't find out.
They briefly experimented with an alert procedure that included "special
alert": if you were playing Jacoby Transfers you would say "alert", if
you were playing something really unusual you would say "special alert".
No one liked this.
So they replaced it with the announcement system: the alerts for
extremely common conventions were replaced with announcements. I don't
remember precisely when this happened, but it was at least a decade ago.

Not sure what you mean by this. You alert *all* NT ranges. The reason
for this is that many players use different overcall conventions over
strong NT (e.g. 15-17 and 16-18) than weak NT (10-12 and 12-14 are
common). That's more than just a 1-point difference.
I think they did this just to keep it simple. If there were a
"standard" range that was unannounced, a lack of announcement would be
presumed to mean they're playing that range, but experience shows that
players sometimes forget to announce things. So they decided to include
the standard range in the announcement. It doesn't usually cause
problems, because it's rare that opener forgets what his NT range is.

Stayman wasn't alerted before they added announcements, so they didn't
make it alertable/announceable when they made that change. The general
progression is that as a convention becomes more common it will go from
being alerted to being announced to being assumed without saying
anything. Stayman and Blackwood are such old conventions that they're in
the latter category.

Cue bids aren't alerted because they're considered "self-alerting": you
couldn't possibly intend it them natural. Although I personally think
they would benefit from being included. Michaels should be either
announce or assumed, and any other meaning should be alerted. The alert
procedure does say that cue bids should be alerted if they have "highly
unusual and unexpected" meanings, but it's hard to know where that line
is (Top-and-Bottom is similar to Michaels, where does it fall?).

Transfers are so common that no experienced player forgets them. They're
taught to beginners now.
