Good point. So, there will be even less of a problem if Shrewsbury are promoted, or rather no problem at all, so it won't bring anything to a head. Apparently for safe standing the seats are locked into place, and then unlocked for all-seater games.If they have converted to safe standing, i.e. rail seating, why would they have to convert it back? Isn't that exactly what we will have in NWHL - a future safe standing area where you currently have to be seated? Or would we have to do something extra should safe standing become permitted?
Do you mean would the Shrewsbury situation have any bearing on whether safe standing would be allowed in the Championship/PL if Shrewsbury were promoted? If so, then no, I don't think it would.
Even if there were lots of support for it and politicians were minded to approve it into law (and I don't think we are anywhere near that level of support yet), parliamentary time is likely to be pretty full over the next few years with Brexit legislative work. I can't see priority being given to something like this. Not for football.
