> Anyone know any other reasons why these crags evaded the radar for so long?
Back when I lived nearby (over 10 years ago) I used to gaze longingly at these walls, wondering the same as you. I'm not sure they were ever "under the radar" as opposed to being "a pain the arse to develop". The topouts are much worse than you allude to, and the compact nature of the rock, as well as the difficulty around Shipwreck (the best new section), means that any new trad routes there would be in the mid-high E-grades. And most people operating at these grades drive straight on through to Pembroke. Finally, they are very tidal and the bottom 2-3m is basically like climbing on barnacles!
Nevertheless, I seriously entertained hammering in a few stakes around the top of what is now Shipwreck Cove, but never got round to it, partially cos I couldn't be bothered, but also because the obvious sensible option was to place a series of bolt belays along the top, to avoid the horrendous top-out. However the bolting policy on Gower was (and maybe still is?) a delicate affair.
Although I'm very happy that there has been development there, I confess I am a weeny bit disappointed that so many sport lines went up. I wonder how many of the routes between 6c and 7b could have been climbed at E4/5/6 - grades which are rather lacking on Gower - just with a nice bolt belay at the top to save the dangerous top out. But having not had the opportunity to climb there yet, and not living there any more, my opinion is not worth very much! Overall, I am delighted that the area is being used at all, and I'm looking forward to going there one day.
