Martynas, the number of triples don't matter. It's the usage pattern that does.
To answer your question about "Because when you decide a DESCRIBE is not enough and you want a custom
CONSTRUCT instead, you simply do that with the triplestore and you're
stuck in the RDBMS setup that you suggest."
In that scenario, export to a triplestore and do what you need. The vast majority of operations (and libraries) will never need or want to do this, though.
And I disagree about using a triplestore for everything and I think it will be a very long time (if ever) that you'll see it embraced by the enterprise.
Regardless, it's counter-productive to prescribe a specific technology if the goal is to increase adoption. Especially if you don't know what the needs and constraints are.

I question I've already asked here, but received no answer to: what's
the ballpark number of triples we're talking about?
Here's a list of large triplestore setups to compare with:
