As IT/network/security, using a well known port for something that’s not what is supposed to run on that port, is inviting all kinds of problems.
Especially the very well known ones, like ftp, ssh, SMTP, http, HTTPS, etc (to name a few). People make it their mission to find and exploit open FTP systems. I opened up FTP on a system once to the internet as kind of a honeypot, and within a week or so, there was someone uploading data to it.
No bueno. Don’t use well known ports for things unless the thing that well known port is known for, is what you want to do.
