Although the following post is probably too old to take into consideration the changing Windows landscape, I'd be willing to bet this request falls under the same context:
https://forums.mirc.com/ubbthreads.php/topics/1109/Non-Windows_version(s)_of_mIRC#Post1109Specifically, if it requires creating a separate "version" of mIRC, it's unlikely to happen, according to the above FAQ. If that stance has changed, hopefully Khaled himself can come in and update to make explicit mention of other Windows based platforms.
As an addendum, mIRC doesn't seem immediately compatible with Desktop Bridge / Project Centennial. It doesn't use an msi installer, so there's that, and many other
of the notes from the porting instructions seem to be problematic. No access to the Program Files..\mIRC directory, CWD issues, .dll support isn't clearly defined, etc. -- at least a few things in mIRC would have to be changed, and to ensure a reasonable user experience, a few features may have to be disabled outright in the Store version or users will be confused about the differences.
Is there value to a Windows Store version of mIRC besides being listed in the centralized store?
