Only minor correction: you can get eight via just the standard installer
- build tools 2017 is not rare at all; while express (yes, "expressly"
discontinued after 2017) is quite hard to find, and you can't get at it
through the standard VS installer - until you actually have it
installed, then the installed VS 2017 installer will let you manipulate
it, but it's invisible otherwise.

the installation policy seems to be you get one toolset version from the
previous major release, only. I don't "know" this (as I've read no doc
or anything), deducing this from looking at my one machine with a bunch
of different VCs installed:

the 2017 VS Installer offers me "2015.3 v14.00" v140 toolset, along with
v141 14.11 through 14.16.

The 2019 VS installer offers me v141 14.16, along with v142 14.20
through 14.27 - note no toolset for 2015 here.


all this is probably getting down to "more than anyone wants to know"  :)
