I occasionally want to, but it may not be important enough. I do find it
useful for display purposes alone, and for finding kinds of test with meson
test --list.

I'd like the buildfarm and CI a) use parallelism to run tests (that's why the
BF is slow) b) show the logfiles for exactly the failed test ([1]). We can of
course iterate through the whole directory tree, somehow identify which log
files are for which test, and then select the log files for the failed
tests. But that's much easier to do then when you have a uniform directory
hierarchy, where you can test which tests have failed based on the filesystem
alone.

bit more debugging enabled crash both firefox and chrome before
