Not true. Parametric EQs let you adjust frequency, too.

Passive room treatment for this (not reflections) seems also very
problematic to me because it's more indiscriminate than the analog EQ.
It will absorb anything in it's range (maybe not linearly) and absorb
the nulls as well.

Not true. Read the info at www.realtraps.com or www.rivesaudio.com
