You still see the full name of the build in case anything fails, so not sure it adds that much value to get an additional box for each cross-compiled architecture, I guess in 99% of cases they will just pass and then you don't really care exactly which platforms you didn't break.. But I'm no UX expert. :)

Ah yeah, just saw that one. I guess just one additional column will still make the table too wide.. Perhaps all the cross builds should just share a single column. :)

Going forward, I do think that the table should perhaps be removed though, and the information should instead be moved down to the "checks" box (just as GitHub actions show them natively - but perhaps condense them a bit just as the current table). The constant updating of the table is probably the major source of the "edit war" you have noticed can occur if you want to edit the PR body yourself while any GitHub actions are still in progress.
