Is your feature request related to a problem? Please describe.
Not necessarily. I have tried porting it to 20w48a, but it always failed. I don’t code, so I have no clue how to fix it.

Describe the solution you'd like
If you could maybe make a way for me to build a 20w48a(20w49a now) that would be great.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
None.
Additional context Not really anything

No. It's an unreasonable amount of work to track a constantly moving target and update our code to it every week.
