I still disagree, I know in the wild you will find poorly written
clients and servers that fall back to plain text when confronted with
STARTTLS stripping, but you will NEVER find software that falls back to
plaintext over direct TLS, because it's simply not possible.
Also I just realized the XEP already spells this out explicitly:
"TLS provides more security than STARTTLS if RFC 7590  is not
followed, as it isn't subject to STARTTLS stripping."
Referring to where 7590 talks about stripping here
Is that sentence as written not correct?
