I think it really depends on the team and map comp.
Sage's wall also is very reliant on the map. You see Sage mainly picked in NA on split (even TSM picks Sage), just because her wall at mid is so crucial to grabbing information and delaying a push for a few seconds. Even though the wall is so weak after past nerfs, there isn't an ability like Sage's wall to play mid safely on split.
You saw how in most Haven games, most of the teams used smokes to exec. Early on in the beta, a Sage wall was used to block off the sightline from either A or C link to allow teams to focus on one side of the B site, but the recent meta has changed to where full control of the site and smoking off both links is more important.
Ascent's map comp is more suited to a team's strengths. For example, Gen.G will sacrifice a sage for gMd's raze because Gen.G's comp setup (and huynh imo isn't strong enough) relies on two entry fraggers, and having gMd not on a entry agent would be less fortunate
I'm surprised less teams are running Sage on bind, though. I think she has a lot of usefulness with her wall on site takes and defense, specifically on retakes or Hookah control
