Why is support for old Windows versions being dropped?

title. I am confused on why this decision was made and it's extremely inconvenient that everything under 1909 is not supported anymore :/

There are some upcoming changes that will require modern OSes:

• Potentially rewriting the frontend in C# / WinForms: Windows 7 does not support multiple CLRs in explorer, therefore if more than one shell extension uses .NET, it just can't work. Windows 8 solves this.
• Changing installer to WiX, and distribution format to MSIX to achieve convenient packaging and context menu entries on Windows 11. This requires the new Microsoft Store, which requires Windows 10 1909.

Since the market share of these old OSes on desktop is less than 5 percent, it's not really worth keeping up two wildly different installers. And it's not like 3.0.x will disappear after a new release.
