The problem is, that determination is often non-trivial to make. Where
is the end-quote -- is the explanation part of the quote of the wording
of the gezeira, or the gemara's explanation of its purpose stated and
stated after the quote?

We discussed this idea many years ago, when I proposed this was the root
of the machloqes about basar kafui.

Very related is that it is also sometimes unclear when something is
a pesaq in existing law, and when a gezeira. If it's a pesaq, then
applicability is built in whether or not it's stated. Pesaqim only hold
if the situation is materially the same. What the gemara says about
putting out a burning house on Shabbos wouldn't apply to a wood-frame
house in an urban or most suburban settings because the risk to life is
simply different. Like the Peri Chadash vs the Chasam Sofer about chalav
yisrael; the PC says CY is a pesaq, so he has little problem saying that
CY is moot when there is other disincentive to adulterating the milk.

Tir'u baTov!
