For a public facing computer, yes, for a private one, not so much[1].

I use mkcert[2] for this but it's still fiddly.

I bought a domain to use for my home network instead. I have LE issue a cert for it via DNS challenge and use it liberally with hosts on my LAN, with the excellent benefit that I don’t need to give clients a new CA I invented.
