Even then the internet (and even books) are full of "godbolt" links, to the tool itself, to specific code samples. Till all those became irrelevant will take quite some time.

As a data point: Search on stack overflow yields "500" hits. https://stackoverflow.com/search?q=godbolt

Links to specific examples are less of a problem as he could redirect those to compiler-explorer.com and just keep that redirect up forever. Really the only URL that would need to be "reclaimed" is https://godbolt.org/ and having a prominent link to compiler-explorer.com thee would solve that issue.

OTOH the godbolt domain is at least not actively used for a number of other TLDs getting one of those might be an easier option.
