Comment (by flixos90):

 While it's a valid topic to raise, I do wonder whether this can be
 considered a bug or an intentional limitation.

 I certainly agree it's unexpected that the original image is not converted
 while its subsizes are converted.

 But before we change anything related to the PNG limitation, we should
 research for history why that condition to exclude PNGs was implemented in
 the first place and whether it's still relevant or can be revised.

 Depending on the outcome of that research, I think we should either remove
 the PNG limitation so that it works the same way for all formats, or we
 could consider disabling it also for the subsizes in that case so that
 it's consistent. Although then one may argue it's still better to have
 only the sub-sizes available as AVIF than all of them being PNG.
