Question to bitcoin devs or other techies here.

Have there been thoughts about temporary soft forks?

In other words, suppose there is some potential change to bitcoin that there is some difference of opinion in even though it seems solid overall. Rather than permanently tightening the rules (which potentially requires a hard fork to undo, depending on the change), is there a case to consider a temporary soft fork instead? Eg it becomes active for the next 100,000 blocks and then will revert to the prior state for future transactions after that point unless renewed again, temporarily or maybe permanently that time depending on consensus at that point?
