I had access to 2k reviews (Low Quality Posts, Suggested Edits) for at least 4 months. Yet, I gave some bounties away which reduced my reputation below 2k, effectively barring me from such reviews. Why should I lose my access to them?

This is probably not a very common issue, but it is rather ridiculous, given the logic behind review thresholds (highlighting levels of experience, familiarity with system/site, trust, etc). It is obvious that reputation lost due to bounties does not deplete those qualities.

Could not this mechanistic approach to reviews access be replaced with some type of checkpoint system, akin to that of badges, which is held permanently?
