Comment (by strk):

 GEOS-3.10.0 introduced GEOSDistanceWithin - performance of using it as as
 good as the `ST_Intersects(ST_Buffer())` one for this case, with no
 downside of needing to construct the buffer, with the related robustness
 issue. PR is here: https://git.osgeo.org/gitea/postgis/postgis/pulls/180
