Should we add this flag to our reco macros too? Better yet, is it time for us to have a centralized function call for our seeding reconstruction?

[sPHENIX-GitHub-l]

First part of the quesion: yes! Second part, what do you mean by centralized function call? On 13.

For example we are not currently calling the function Tracking_Reco_TrackSeed() in our reconstruction macros, e.g. here. The seeding may be at a point where it has converged enough to have it a central place, which would also make it such that we would have a consistent set of modules/flags that the macros by default call

[bogui56]

Ah, that way, well for me that would be ok. Modulo the changed Michael and David will still come up with...

[osbornjd]

It does cause a small loss in efficiency at low pT

but that is probably not an issue right now
