Alacritty is a cross-platform, GPU-accelerated terminal emulator.
It is focused on simplicity and performance. The performance goal means it should be faster than any other terminal emulator available. The simplicity goal means that it doesn't have features such as tabs or splits (which can be better provided by a window manager or terminal multiplexer) nor niceties like a GUI config editor.
The software is considered to be at an alpha level of readiness--there are missing features and bugs to be fixed, but it is already used by many as a daily driver.
Why should this be included in the repository?
It's a great terminal emulator that has just landed a crucial feature (scroll-back) and offers nice performance. See the creators blog for details: https://jwilm.io/blog/alacritty-lands-scrollback/
Sure there many other terminal emultors around, but GPU acceleration and simplicity (configuration through config files, no window decorations / menu bar) are nice-to-haves and make it especially useful for tiling WMs.
Is it Open Source:
yes, Apache License 2.0
Who and how many users do you anticipate will use this software?
Hard to say, but judging by Github-stars it's pretty popular or let's say "highly anticipated". I'm sure a couple of people already installed it using rustup but a package would be much nicer obviously.
