I use dockerized cron script that periodically renews my letsencrypt certs and haven't had troubles with it since I set it up.
Well... once I was messing with dns and messed it up, but that was all my fault.
It was a bitch to set up, though, but now I just copy/paste it wherever I need it.
hah, yeah, that's my point, it's rate limited, and if i want to spawn infinity subdomains, i answer to nobody else if i own a wildcard certificate outright, rather than a freebie from some NGO
the prices are extortion but obviously low enough that i can justify it for a domain i plan on continuing to use well beyond then, and for which i require to be able to make infinity subdomains
i suppose if there was an actually decentralised name resolution protocol it would cost something, and spammy registrations would probably be part of that cost, in mitigation, so it's probably not that far from what it really is worth
i has it now so i can uses it
