you're right, but the problem is, you rarely need utility DD (except Tashkent with her 4 slots). Johnston can't do her strong AACI if she wants to do OASW as well for example (the same reason people rarely use Satsuki for both AACI and OASW, her AACI with only machine gun is too weak). When you use DD, you want her to excel at her job, not doing both so-so jobs (unlike Yura who can secure AS while DA at night, because for AS you only need a hallmark)

Indeed sometimes we can use a not-so-good AACI alongside not-so-good OASW, like in 6-3, but even then I want night gear instead of sonar. For 5-5 you'll want a committed DD for OASW (aka sonar+DC+DCP combo, or at least sonar+DC) if you want a S-rank, and for 6-5 you'll want a strong AACI (aka full set).

So in short, she is benefical to a 100-slotter for example, because she can be good at many jobs, but one at a time.
