I should have made clear my higher level argument: Windows OS and its internals won't allow it to be comparable to the experience you'd get from an OSX andLinux if you are a person remotely interested in Information Technology, and it's an increasingly larger demographic for a product like this.
POSIX compliant is critical for those who do things related to web development. There's a reason why very important tools and libraries critical for web development today such as Tmux. RVM, and etc.
It's common knowledge, you're doing yourself a huge disservice using Windows instead of Linux or OSX for web development.
Given the fact even front-end design and development expectations expect people to be more involved with code than ever before instead of static images to be more efficient, Windows terminal is completely underpowered compared to Linux and OSX. It's insufficient and yet they continue to do things their own way with no benefit.
Try enrolling to any serious web development or web design program with a Windows laptop expecting to use it throughout the program; at best, you're far more inefficient than your peers and often can't use what they can to be far more proficient web developers. .
