bug#59996: 30.0.50; Overlays section of Elisp manual still states that overlays scale linearly

[Ihor Radchenko <yantar92@posteo.net>]

Hi,

I am still seeing the following clause in the 41.9 Overlays section of
Elisp manual:

       The visual effect of an overlay is the same as of the corresponding
    text property (*note Text Properties::).  However, due to a different
    implementation, overlays generally don’t scale well (many operations
    take a time that is proportional to the number of overlays in the
    buffer).  If you need to affect the visual appearance of many portions
    in the buffer, we recommend using text properties.

Should it be removed now, when overlays are equally performance with
text properties?
