The entire description of the "fall" described in the link is:
> Since those heady days, Preview has been relatively neglected. Revision of both the Quartz PDF engine and its API brought a spate of bugs that only abated with macOS Sierra. Preview has adopted an uncommon model for PDF annotations that doesn’t work well with other PDF products. Then, in macOS Ventura, Apple removed all support for EPS and PostScript conversion, most probably as a result of ongoing security concerns, and their progressive disuse.
I haven't noticed bugs, annotations seem fine, and EPS/Postscript conversion isn't really about Preview at all.
Sure Preview hasn't been gaining tons of features, but it's a pretty mature app that arguably doesn't really need much else.
