But - most Linux hosts with cPanel have this facility
Although it is true that most Linux hosts with cPanel will show this as an option. In many cases, when you click the icon you'll be created with a pop-up saying the feature has been disabled.
It rather sad really because there really isn't any need for such restrictions, but a few/many years ago there were some serious vulnerabilities with the MSsql server (MicroSoft) and the 'cure' was to block remote access. Although the vulnerbilities have long been fixed (and was never an issue for MySQL) a lot of Network admins still perceive it as a security risk and no amount of logical arguments or facts can convince them otherwise. :(
I can't give percentages, but I've found that there seem to be more hosts that deny this than there are that allow it.
