question to implementation for ModernBertForMaskedLM vs ModernBertForSequenceClassification

hi,

where can i find more infos to how ModernBertForMaskedLM needs to be implemented? i saw an implementation for ModernBertForSequenceClassification here:
https://github.com/vllm-project/vllm/pull/16648

also, can the ModernBertForMaskedLM be used for a classification task?

Thnaks,
Gerald
