Exacly. And that’s why we/them/everybody needs one setting more.
Sure, if the real reason not to limit ability of mentions is it will break too easy background jobs (again, as an example) like messaging of team or what ever works there, that is understable.
I’ve worked on live support and sales. I didn’t do very much global markets but scandinavians. But britons have real strong tendency contact right away to superviser if theirs demands didn’t fullfilled. That’s why email addresses and phonenumbers were’t available at all for customers. We didn’t rely on asking customers not to bother them because they had some other jobs to do too.
Same apply with limiting mentions. Different environment, but totally same principle.
