Is it bad idea security-wise to use basic roomnames like 'meeting' on your server even if you use Secure Domain plus lobby (so without a password)?

I remember in the ‘early’ days when Zoom’s popularity exploded but there were a lot of security issues, and thus I switched to the Jitsi side. I don’t want stuff happening like someone can ‘hack’ my server and eavesdrop, record, etc. my meetings even if they don’t manage to show up in the actual meeting. I’m using UFW like the docs say.
