Hey there :]
as someone still using termite today, thank you for your hard work.
Please note, that there is actually still a use case for VTE-based terminals: Many laptops popular with the libreboot crowd are based on the GM45 chipset with the GMA4500 iGPU (Thinkpad x200, T400, T500...), which does not support alacritty's requirement of OpenGL 3.3. (Though there is an alacritty branch which addresses this....)
Especially for Wayland users, VTE based terminals always just worked.
But moving on is also part of software I guess, so many thanks for the years of excellent support.
