Perhaps starting with 6, could you always have 2 digits in the minor version (i.e. 6.00, 6.01, etc)? That would probably reduce winget's confusion about, for instance, 5.10. It knows that 5.10 is the current version, but seems to drop the zero and treat 5.10 as 5.1. That results in it downloading and reinstalling 5.10 every time I run an update check. Possibly related to the bug that forced skipping from Windows 8 to 10 - something would have treated a Windows 9 as 95 or 98. Having 2 digits with the leading zero should fix it if that's what's happening.
