We do hold like Ben Zoma regarding zekhiras yetzi'as Mitzrayim at night, and
it's true (see the Tosefta brought on Berakhos 12b) that Ben Zoma holds that
there will be no mitzvah of zekhiras yetzi'as Mitzrayim in yemos hamashiach.
In essence, both Ben Zoma and Chakhamim have the same starting point -- an
assumption, based on the pasuk in Yirmiyahu, that the mitzvah will not
apply.  Chakhamim override that with a derashah, which forces them to
reinterpret the pasuk in Yirmiyahu, but Ben Zoma uses the "kol" for
something else, so he's left as a maskana with the position that was the
hava amina of the chakhamim.

But is that starting assumption really so self-evident?  Most other mitzvos
don't have special derashos teaching that they will still be applicable in
yemos hamashiach.  Is it possible that we hold like neither Ben Zoma or the
chakhamim, but rather like a third shitah (not explicitly brought in the
context of this mitzvah, but perhaps implicit from positions elsewhere) in
which the "hava amina" never gets off the ground, since this shitah
maintains that mitzvos will never be abrogated, and therefore the pasuk must
be understood in a "watered-down" fashion -- much like the maskanah of the
Chakhamim, but without needing a special derashah to get there?

If this were the case, we could hold like Ben Zoma on the question of
zekhiras yetzi'as Mitzrayim at night, but like this third shitah on the
question of yemos haMashiach, and there would be no contradiction.

Alternatively, isn't it possible that we could simply accept the dinim of
both Ben Zoma (night) and Chakhamim (yemos hamashiach), even though we don't
know which one of them was correct to use the ribbui of "kol yemei
chaiyekha" as an asmakhta?
