..but they’re not considering any more extension requests?
Sure, but they've said that before. It's politics.
The UK has the unilateral right to revoke A50 but they can only do so in 'good faith'. They shouldn't just do it to buy more time.
Revoking it, and then having another referendum(s) or a GE specifically fought on a "vote for us and this will be your Brexit" mandate would satisfy the EU that the UK is acting in good faith and now has internal support. (I wouldn't give it much chance at all that the Government could put something out there that would gain a majority support from the public. All of which would hopefully default us into remaining and the country can begin the long process of getting over itself.)
The Tories (thankfully) fucked up massively by calling the snap general election in 2017. If they'd stuck with their slender majority (propped up by bribing the DUP in the same way) then they would have probably been able to push through the WA first time round and we'd be out by now. *shudder*
None of the outcomes (Hard brexit, soft brexit, Norway+, BRINO, Remain, etc) will "bring the country back together" as it is just too split on this binary issue so there is little point in looking for a more perfect solution.
One outcome that's a possibility is a stooge to be put up as Tory Leader to revoke A50 and "give the country some time to heal itself" and better prepare for another referendum on EU membership in 3-5 years' time. One huge kick of the can much further down the road. Once they've taken the flack for that and the public have got used to that idea they can give way for the real new Tory Leader who isn't tarred with that shitty brush.
