On the projects I've hacked on, a lot of time has been spent trying to replace bash and autotools in the build process and reduce its usage. They are brittle and nobody really likes to maintain giant shell scripts filled with fragile regular expressions and other unreadable awk invocations. Plus I've lost count of the number of build scripts I've seen that do strange things like failing to handle spaces in paths because something is not escaped correctly. They are really not a good solution. This can be caught with CI, but if you use any kind of CI then you have even more incentive to get rid of it because bash and makefiles (which fork an additional shell on every command) are very slow.
