Is it normal to use these technologies
There is a tool.
It solves certain problems.
From the date of this task list is not affected.
If you have these tasks in the project you use it.
If you do not have these tasks in the project - you are not using it.
If the project is already a tool that solves these problems - you another with no good reason not to bring.
So look, what do you have for the project, what objectives are, what tools will be used anyway, and then decide whether you want to add something else. No need to bring in or to throw out the tools just because of the hype or some of the kinks of the type "it is outdated". Out of many standard Linux utilities older than me, but they both solve their problem and continue to solve it. In the front the same - age tools do not lose their functionality.
