After a command such as -regress-, you get matrices returned in e(), such

I would like to refer to a particular element of e(b), but I can't seem to
do it directly. I can refer to the whole of e(b), but not to e(b)[1,4] or

The only way I seem to be able to do it is to copy the whole matrix:
mat M = e(b)
Then I can refer to M[1,4] or el(M,1,4).

Is that the only way to do it?
Yes. This has always been the case.
