Deprecate code support for HGCal v8

[kpedro88]

#26938 includes removing the HGCal v8 geometry, which does not have the variable silicon/scintillator boundary and uses the old DetId scheme (HGCalDetId for EE/FH, HcalDetId for BH). Once this geometry is no longer supported, we could consider cleaning the code to remove the proliferation of switches to handle this old version. This would greatly simplify future development.

HGCal v9 is now deprecated as well, so further usage of HCAL objects, etc. can be cleaned up in the code.

@kpedro88 - please, let us know if this issue has not been addressed yet. Thanks!

[kpedro88]

It has not been addressed as far as I'm aware.

It has not been addressed as far as I'm aware.

how about now?

#32397 removed HcalGeometry from the HGCal digitization.

There was some discussion that parts of the old geometry support had to be kept for test beam studies.

@bsunanda @rovere should comment about further cleanup plans.

Hi @bsunanda @rovere
Could you please comment about the next cleanup plan? Thanks.

[ianna]

@kpedro88 - please, let me know if this issue is resolved. Thanks!

[kpedro88]

@bsunanda is there more cleanup to be done for this issue?

[jbsauvan]

Hi
There's actually also some cleanup to do on the HGCal trigger part, which I've planned to to for a long time but never took the time to do it.
I could realistically clean before August the old v8 code there.

[jbsauvan]

Regarding the HGCal trigger part, the deprecated v8 code has been removed in #34608

[jfernan2]

Is this issue still valid?
