This list can become very clustered with abandoned addresses, and can make finding specific addresses more difficult.
Deleting addresses should require the password if the wallet is encrypted.
Hiding an address would be preferable, just in case a person receives a transaction to one.
Deleting addresses will never be supported, hiding would indeed be useful.
Perhaps being able to mute addresses as well, in the case of micro-payment spam. (Though I guess if they know one address they can fairly easily find the rest of them if they're used.)
More than 1 year has passed and we still don't have this feature?
As long as no one is interested in implementing it, it won't happen.
Making suggestions here is just an idea box for (potential) contributors, it does not obligate anyone to take action of any kind.
Not sure if I understand the feature correctly:
By supporting multiple labels we could have internal labels like "__hidden"? getaddressinfo already returns labels: [].
Let's continue discussion in #17174
