I think a lot of new entrants to previously-well-explored spaces tend to label themselves as "modern" in order to signify that there is something new about their approach.

For instance, I have a migrations library that I descibre as "modern" because it is designed for a continuous deployment environment where you're automatically running migrations on container startup — there are tons of existing popular migrations libraries, but none of them work this way because they were written in the era that you'd manually run sql commands in prod. I say "modern" so that if anyone finds my library, they realize that it was created recently based on more recent dev/ops trends.

Maybe I should drop the "modern"? I do see a lot of people describe their code as "minimal" or "clean", which is pretty meaningless to me, so I get that "modern" could come across that way as well.
