Customer service was unhelpful and downright rude.
Never had any problems with Namecheap.
After raising this issue last February, they said it was coming soon. A year and some more of no action later, I transferred all my domains out since using known-broken security apparently isn't a priority for them, and it probably reflects in other and harder-to-see ways.

'Not yet', is my answer.
Could you give a summary how this happened?
There was an issue with their transfer authorization emails -- one was never received, another to a different email (having changed email in the WHOIS) was received and authorized but their system never acknowledged as much.
The transfer ultimately never happened, the domain lapsed and was snapped up by someone else.
Their support were unhelpful, argumentative, and acted like they were doing me a favor by refunding the fee for a transfer that never happened, all while they lost my (quite valuable) domain.
Never again.
I've used Gandi before and I recommend it.
