@mark-grimes, @fratnikov I wonder why it is not yet merged. Thanks

[fratnikov]

Two reasons:

1. this is XML, so doesn't affect nightly builds. v6 is not in RelVals.
   Thus this waits until further progress with v6
2. modified file doesn't look specific to v6: is v5 intact with these PR?

[vandreev11]

@fratnikov 2. v5 is in tact, in the sense that v5 geometry is frozen and is not affected by v6. Particle Flow needs to be synchronized.

This affects nothing than v6 HGCAL indeed
