Worse plug how? You can buy DP cables without the locking mechanism.
Go to your local electronics store and see if that is true when you want a cable “today”.
There’s a difference between theory and practice.
Different countries and regions may have better markets for DP cables, but I can’t recall having had options other than length.
Why would you even want that, the locking mechanism is imo one of the advantages DP has over HDMI, I had one too many instances of the HDMI plug getting lose in the socket causing signal loss (granted, not a big issue for Home Theater but def. an issue for some people for PC usage).
YMMV, obviously.
Locking DP is a pain in the ass for me. HDMI disconnecting was never an issue either.
I just wish I had a choice, but in practice I don’t as selection of cables is poor.
I never screwed in VGA or DVI connectors either.
Personally I prefer the plug falling out instead of the connector and/or cable getting damaged if you pull on it.
