 Thanks for asking!

 I can indeed confirm that even not the latest 16.8.2 versions of MSVS 2019
("169.1" above must be a typo and "16.9.1" was probably meant instead)
supports designated initializers, at least in the simple use cases, so it
should be fine to use them. And I'll try to test them in the real code,
with MSVS, when you push the changes using them.

 And no, I don't see any other reason to avoid them. Admittedly, I don't
have much experience with them, as I've only encountered them in Linux and
gcc-only projects so far, but they do look useful.
