You mean to break the chain introducing an intermediate step

With intermediate step, I mean a new kind of entity with its own format

I like the idea

Many times, breaking long chains makes them more understandable to me

It's the old idea of composability, if you want

It's like refactoring a huge procedure in several smaller ones

It also resembles a sort of ETL process or some sort of "data science"
task of "massaging" data for some later analisys phase

In a way, doing this would in itself push language communities to think
about their approach (of releasing blobs)

I doubt they would start such an initiative themselves, they wouldn't
have begun releasing blobs in the first place
