I wonder why all the major hardware wallet companies are slowly...

Are slowly taking away the ability to perform message signing and verification for P2PKH addresses? As far as I'm aware all of the other address formats have no standardized way of confirming address ownership which makes this even more concerning since the only one that does (P2PKH) is slowly being taken away for support for all of the main hardware wallets of today.

Ledger took it away a few years ago when they got rid of their standalone chrome wallet (with no reason given as far as I know), Trezor recently removed this feature when they disabled their web interface (they had P2PKH signing on their web interface but pulled it from their standalone desktop download), and even Cold Card says on their website that at some point they may be disabling the use of P2PKH in the future.

I understand that P2PKH addresses use more block space than the others, and I understand that they are more expensive to send than other formats however considering the trade off of not being able to sign messages from these addresses in a universally accepted standard between wallets (or BIP) than I think the self sovereignty aspect here way outweighs any downsides for P2PKH address uses and I don't think the wallet companies should be dictating how we use bitcoin.

At this point in the game not only should all wallets (software and hardware) be fully implementing and supporting P2PKH message signing, (which is a standard and not wallet specific online some signing for SEGWIT addresses,) but they should all have the ability to directly connect to your own nodes so that you don't have to rely on these companies for their nodes ( and not through middleware either). I mean who knows who really runs these nodes and what their motivations / agendas are (AML/KYC? insert your own theory here..how would you know if it's not your node?).

Either way this seems like a serious attack on the self sovereignty aspect of bitcoin and perhaps may even be something much more sinister. To further the self sovereignty I truly hope there is also some serious efforts underway to make a user friendly blockchain explorer you can simply add to your own node if you have the TXINDEX 1 in your configuration file. This would help all be more self reliant rather than depending on your favorite web hosted third party blockchain explorer.

As always I'd certainly like to hear any thoughts about this. Have a great day fellow bitcoiners!
