Video Encoding Photo PNG + Alpha Accepted Again or Not

Hello,
now I saw in the section “Stock Footage Requirements / Video Encoding” it is written that the format “Photo PNG + Alpha” is accepted. I ask because the files in this codec become more tolerable size than the “Apple ProRes 4444”. I know that for about two years, as far as I remember, it was announced that files with an alpha channel in the “Photo PNG + Alpha” codec are no longer accepted.
The information in the “Stock Footage Requirements / Video Encoding” section was last updated 4 months ago!
This will confuse many people.
Thanks for the help!
