I've read a fair bit about re glazing old windows. Everyone, including
the instructions on the back of the DAP 33 container reccommends oil
based primer. I have plenty of latex primer and with oil based paints
being phased out in general what type of glazing compound should I use
with a latex primer?
And why does DAP reccommend oil based primer?

DAP suggests oil based primer because it works better.
I have also brushed on several coats of boiled linseed oil to prime, ahead
of puttying. It fully saturates the wood, allowing the putty to take a
proper "set", and slow the drying/aging of the putty. Oil paints for this
purpose are not being phased out, and will likely be with us for a long
time. Boiled Linseed is not particularly toxic - comes from pressed
flaxseed - and is a great wood preservative when used on porous wood, under
a coat of oil finish paint, or oil based putty.

The wood preservative aspect is only important if you're not doing the
required maintenance, that is, painting on an as needed schedule. Wood
protected by any paint film in good condition will not rot. Neither
oil or latex paint will eliminate maintenance. If you're not going to
do the required maintenance, the wood windows should be replaced with
something not requiring maintenance. Considering how much work is
involved in priming, glazing and painting a wood window, and the
ongoing maintenance issues, it might be worth consideration to start
replacing windows one/few at a time.

I do agree with another poster's comment to the OP about using a latex
glazing compound if you're going with latex primer and top coat. No
compatability questions that way. I can only blame my omission on low
blood sugar.
