Is not about the wallet interface.
Is about the LN implementation that allow that feature.
Until now, NONE of them (LND, CLN, LDK, Acinq) let you do coin control when is about to open a new LN channel.
Don't look at the wallet apps level, they depend on LN implementations.
You can definitely specify UTXOs to use in Core Lightning channel opens. It's long been available by CLI, but RTL now also has a nice UI for coin selection.

There's a lot of flexibility available. You can even batch channel opens together and fund them externally.

Yes they do. It's the PSBT opening flow. You can open channels from cold storage funds.
LDK ONLY let's you do it via external funds too.

LND too
Please show me a demo how I can do that (selecting a specific UTXO) with LDK (Mutiny, Bitkit, Bluewallet).

I made this guide years ago for LND: https://abytesjourney.com/open-batch-channels-from-cold-storage-using-lnd-electrum-and-coldcard/
LDK is a node library, not a wallet interface. To do it with LDK, it is here: https://docs.rs/lightning/0.0.118/lightning/events/enum.Event.html#variant.FundingGenerationReady

OK that is good.
Now try to translate that to a LN noob (are many here) that just want to do some few clicks in an app (for example Mutiny, Bitkit, Bluewallet)

If anyone has support for it, it's probably Zeus. I don't know any LDK based wallet that supports selecting UTXO for channels yet, but I know all node implementations support it. I was just commenting on that.
