Trusty daily trusty-proposed updates?

[Erick Brunzell]

According to my calendar 14.04.4 is tentatively due February 4th:

https://wiki.ubuntu.com/TrustyTahr/ReleaseSchedule

So I gave the Ubuntu GNOME 20160124 amd64 daily image a quick bit of 
testing and I notice that trusty-proposed is still on via 
/etc/apt/sources.list.d. Is this intentional?

I'm particularly curious if all the updates included in trusty-proposed 
have passed the proper SRU testing. I seem to recall running into 
trouble with this a few cycles back.

Thanks in advance,

Lance
