I appreciate the appeal to authority:
But, he who seems to know a bit about "sharpness" (Digilloyd) ... to which I'll add "acutance" ... also wrote an article on the removal of the AA filter as performed by the author of the referenced article. In THAT article ... well, let's just say that you might want to read it for yourself, also.
HINT: Some might suggest that one authority is actually confirming the other authority on the matter.
But, here is an excerpt from Digilloyd:

Mind you, this is tested with the Nikon D700 which has a pixel density very similar to the Kodak SLR/C, but in talking about the 80D, we are talking about a very different pixel density. Imo, this variance in pixel density only serves to REDUCE the concerns associated with a non-AA protected issues. But again, if you value Digilloyd's opinion, see above. That's not to say the issue(s) are non-existent EVER, but depending on what you are shooting (or more importantly, not shooting), it doesn't seem to bother Digilloyd with regard to other cameras that do NOT have an AA filter.
Also, in the LL article ... there is a lot of dialogue about "attempting" to de-convolute the math, and even includes discussion about AFTER downsizing to perform such de-convolution, etc.
Imo, this still remains an issue of Deming 101 ... risk / reward @ choose your (potential) poison(s).
Imo ... in the end, there are two (primary) ways to approach this. As such, we have options @ diff strokes, for diff folks.

I was unable to find his review of a Zeiss lens on an AA-less camera where fine white tree branches against a black background were covered with colour noise from the lack of AA because the size of the twigs was similar to the pixel size and the lens wasn't limiting . He also had some ugly moiré examples from AA-less sensors. He understands the pluses and minuses of AA filters and his comment on the deconvolution "pretty amazing really" was the main point of the post Also, AA filters are designed to make the 4 sharp images land on the corners of a square with a side of ~1 pixel, so their thickness varies with pixel density - and the need for AA goes down as pixel density increases because lens and diffraction ;limitations do its job
