previous description:

• As jet clustering is done with a MarlinProcessor, the lcio files must be converted into edm4hep files afterwards. The writing of this file breaks because of the different formats expected by edm4hep compared to lcio.
• Therefore, we use the available resources for the conversion to fix this: https://github.com/key4hep/k4EDM4hep2LcioConv/blob/main/doc/LCIO2EDM4hep.md

Thx a lot!

Some change requests are below.

We could consider applying the patching in any case, e.g. also when writing out lcio files to ease future conversion. @tmadlener is there any specific reason why you opted to not do this in ILD?

If we are being generous we could interpret it as "not changing existing behavior for LCIO output". Simply not thinking about it is probably the more honest answer here ;) (Additionally, at least for ILD the only remaining issue are the potentially missing ParticleID objects, the collection contents have been fixed already by fixing all relevant processors).
