Do we think that this vanishes before it has any meaningful effect? I mean, regardless of what's happening abroad, we're not going to be able to do much before lockdown ends. And even if it ends in England, doesn't mean (unfortunately) the rest of the UK will see it end. We're not going to be allowed to travel abroad whilst lockdown restrictions are in place (is whilst majority of businesses and gatherings are still banned)
By which time various parts of the world have also seen recovery and air bridges have been opened to Europe, US and other major UK travel destinations. Thus rendering the policy, which is basically to discourage travel either to or from the UK, useless.
