[Avodah] halachik status of siddur

[Eli Turkel]

Do the ideas of any piyut incorporated into a standard siddur or
machzor now have legal status that rejecting them is now problematic???>>

The halachik status of sayings in the siddur is very unclear.
A famous example is the Brisker psak that one cannot add a day
for the Holocaust based on a kinah for Tisha Ba-av. Other more
haskafic questions are Prayers on Rh-YK that talk about
G-d determining what will happen in the coming year. According to
most rishonim that G-d only decides for tzaddikim this tefilot are
not le-halacha. Similarly prayers on RH-YK that the world was created
on RH are not necessarily psak but it is debated
