It's not common. If `kill` on its own (which does just SIGTERM) doesn't work, you're already in "something wrong is happening" territory, which is why:
>>> Given that this is the right way, it shouldn't be more tedious than the wrong way!
is also the wrong way to think about this. Trying a sequence of signals is not so much "the right way" as it is "the best way to handle a wrong situation". The right way is just `kill` on it's own. SIGTERM should always suffice. If it doesn't to the user's satisfaction for a nonjustifiable reason, then you can just `kill -9`, but this should be rare.
Trying a sequence of SIGINT, SIGHUP, and SIGABRT is technically better than SIGKILL but not really important unless you also want to write a bug report about the program's signal handling or fix it yourself. About SIGINT and SIGHUP, if SIGTERM doesn't work, it's unlikely that SIGINT or SIGHUP would. Likely, it would only be through oversight and the execution of default handlers.
`kill -9` is just like `rm -rf`. I wouldn't suggest that `rm` automatically run with `-r` or `-f` when `rm` on its own didn't work, and I wouldn't call automatically trying those flags "the right way".
