Absolutely. I worked a codebase that was littered with ticket numbers for a few years; many members of the team religiously added them but never read them. How do we know? Self hosted issue system and access logs. New starts would read a couple and that was it. A ticket is a really opaque way of showing something. If you click the issue you're now going through several tangentially related comments and a few MR back and forths just to work out if its even useful to you. People will stop bothering to even open the link unless they are really stuck. Whack a summary comment and then by all means include the link, but the comment is what most people will use.
