Let me give a partial approach.

According to "my" hesber in SA
Water added to mei peiros BEFORE leesha is bateil - regardless of the
various scenarios.
[So too Rif and Rambam]

So the ONLY problem is taking mei peiros - kneeding a bit with flour - and THEN adding H2O.

And according to my hesber of Rema - he concurs mei'iqqar hadin - but
is chosheish l'chatchilah that drops of water added before leesha
MIGHT be a concern - albeit not enough for Bal Y Bal Y but for achilah

Schoen - it all makes some sort of sense.

Of course you might ask - NU so what if kneeded first and THEN water
comes in later. Good question and one needs to see the posqim inside
and see that there is some kind of ch'shash that since mei peiros are
not machmitz once water has been added it might be neglected.

At any rate, some hesbeirim are slightly less "magical" then others.

EG Rashi rejects that kli sheini is never m'vasheil. As he sees it -
when the water was heated [hotter] for washing instead of for drinking
It indeed CAN be m'vasheil. Because as per Rashi it's not a magical
legal construct, it's an observtion of typical m'tzius.

Here too. Some will posit more "magical" legalisms, and others will tend
towards more m'tzius oriented explanations

Even so not even the m'tizus crowd denies all legalisms. EG "lo plug"s
can make issurim in places where the specific m'tzius indeed would be
far-fetched. For matzah that includes "s'riqim" [molds] even "s'riqei
bayssus". Etc.

And so the humros or minhggim re: matzah ashirah and qitniyyos probably
include scenarios that would never trigger real ch'shash of hametz.
EG raw, dry qitniyyos or dry roasted qitniyyos.

I hope this helps
