To some degree and this is true for all heterogenous mixtures in solution(water).
We have some that act to counter the other, some that act synergistically, some antagonistically etc.
It can be a mess in real "field systems", vs the lab isolated situations.
Folks seldom make this distinction when applying research from the lab.
However, since some plant tanks add CO2, this might be worthwhile and not deal with higher pH's.
I think given that having some KH(50-100ppm), vs say, super soft water(5-40ppm)............might help and then not haver the issue with higher pH's.
There's a balance essentially.

There's a lot of plants and good bacteria, the NH4/NH3 really should not be an issue is a well run tank. Should not be much there.
