This doesn't look like something impossible to do, just like a missing
feature in bash.

That doesn't seem so simple to do to me.

What are the missing features in bash for writing easily, safely
re-usable bash code?

 

Without thinking too much about it what comes to my mind immediately:
 * bash has only one name space for functions, so it's easy to overwrite any function used in a module.

* There's only one name space for global variables 

* There's a gazillion of options (shopt and set) to globally modify bash behavior (including parsing)

I don't think it's comprehensive by any measure

 

Could bash be extended with these missing features?

 

Maybe but I thought the most interesting part of my email was where I said that I don't think it prevents someone from making such a repository now,

and that by starting now it can bring some good things such as some guidelines and coding style guides.

I will even go as far as reverting your point of view: starting such a repository might help to identify what new features would really help .

In many projects what is lacking are not the features and a big list of  "must have" but someone starting to do the actual work. (And no I don't volunteer)
