should also integrate with nominees-election to allow LDOT holders to elect validators

reviewed the designs of nominee-election and homa-validator-list. They are similar. It seems that nominee-election is an earlier design. Later, there was the pallet homa-validator-list. Similarly, LDOT holders can give validators Votes to increase its guarantee, and the locked guarantee can be frozen and slashed through governance

Need to confirm, is the design of homa-validator-list enough to replace nominee-election? Does it need optimization, or some renaming?

This is the intended usage:

Validators what wish to become LDOT validators needs to register themselves using homa-validator-list and provide insurance deposit.

Then LDOT holders can nominate LDOT validators using nominee-election to pick the top X validators out of all registered validators from homa-validator-list

So the deposit for homa-validator-list can be low as they have to be top X picked by LDOT holders anyway

I understand, homa-validator-list serves as a filter, and the pick up logic should be placed in nominee-election, and homa read nominee from nominee-election.
