No problem at all!
Whilst I completely understand your frustration, I have a lot of empathy for developers who've had to do the same for so many of their existing extensions.
I was in the middle of developing a package of extensions incl. a component for Joomla 3, module and several plugins, when I had to halt the project. When I came to resume it, J4 had been released, and I realised it was senseless to continue. So, I upgraded all of the codebase for v4, and refactored a lot of the plugins to make it more modular. It was quite an arduous task.
Anyway, I wish you luck, and hope you get it sorted soon!
