Any well-known generic word is very likely to already have been used by a bunch of projects, some of them already prominent. By now, the best project name is a pronounceable but unique string, for ease of search engine use. Ironically, "systemd" is a good name in this regard, as are "runit" or even "s6".

Are you sure? There are lots of words, and not so many projects that use words like these as their names.
Of the 118179 packages I see on this Ubuntu 18.04 system I can roughly roughly ask how many have names that are dictionary (wamerican) words:
comm -12 <(apt-cache dumpavail | awk -F': ' '/^Package:/{sub(/^lib/,"",$2); print $2}') /usr/share/dict/words | wc -l
I use tiny init systems regularly in AWS Nitro Enclaves. Having the enclave and init system both named nitro is not ideal.
