The consequence of explicitly removing `-latest` (as you mentioned in the
commit message) is the addition of the new `os` field just to remove that
suffix (+renaming 'macos' to 'osx' to - I assume - save a bit more space).

Keeping the `-latest` doesn't really seem to hurt your goal of improving the
tooltips, though; worst case, the `-latest` would be what's cut off in the
tooltip. The main reason I bring this up is because I'd generally prefer
reusing existing fields wherever possible - e.g. something like this: 

    name: ${{matrix.vector.jobname}} (${{matrix.vector.pool}})

...which has the added benefits of 1) fully reflecting the agents used
(potentially beneficial e.g., if we switched from `macos-latest` to
`macos-10.15`) and 2) better matching the way you've set up the docker
image-based jobs later on.

Overall, I like the fact that platform info is retained in this version
(while also managing to shorten names and/or make the non-truncated parts
more helpful). Thank you for the update!
