Bug summary
Updating RC params in code produces a deprecation warning. In order to control rcParams for an internal library I am reading in parameters and popping some that I don't want used. I am using a variation on the code below. I think I have traced it to the _validators dictionary in matplotlib.rcsetup.py
Code for reproduction
This code reproduces the error.
import matplotlib as mpl
rc = dict(mpl.rc_params())
mpl.rcParams.update(rc)Actual outcome
C:\Users\User\miniconda3\envs\testmpl\lib\_collections_abc.py:841: MatplotlibDeprecationWarning:
The datapath rcparam was deprecated in Matplotlib 3.2.1 and will be removed two minor releases later.
self[key] = other[key]
C:\Users\User\miniconda3\envs\testmpl\lib\_collections_abc.py:841: MatplotlibDeprecationWarning:
The savefig.frameon rcparam was deprecated in Matplotlib 3.1 and will be removed in 3.3.

C:\Users\User\miniconda3\envs\testmpl\lib\_collections_abc.py:841: MatplotlibDeprecationWarning:

C:\Users\User\miniconda3\envs\testmpl\lib\_collections_abc.py:841: MatplotlibDeprecationWarning:

C:\Users\User\miniconda3\envs\testmpl\lib\_collections_abc.py:841: MatplotlibDeprecationWarning:

self[key] = other[key]
Expected outcome
I would expect Matplotlib to not load deprecated rcParams
