That's nothing new. When I wrote
1234. 2,
and the system did not complain, I expected "2," to be a word (along
the lines of 2@ and 2!), but it actually was recognized as a number.
And concerning LOCATE,

I think that, in practice, it will be made clearer. We can let
'abominations like S"' fall into disuse and eventually destandardize
them, and, more importantly, have a good alternative to introducing
more such abominations.
Of course, you can dream up all kinds of abuses, and there will
certainly be people who will experiment with that (and we will come to
slightly different opinions of what constitutes abuse and what
constitutes desirable usage), but the abuses won't catch on, so no
need to worry about that.
