17 Note that the revocation certificate is still listed under
18 recommendations only, so devs need not create one. Making this a
19 requirement would be a real improvement, IMHO.

21 Instead, the GLEP draft is focusing on short expiration times.
22 It won't help much if your compromised key will expire within one
23 year, but you cannot revoke it.
24
25 Suggestions:
26 - Change the minimum requirement for key expiry to at most 3 years
27 (which is what in version 1 is recommended).
28 - Recommend at most 15 months of key expiry, to be renewed at least
29 2 weeks before the expiry date.
30 - Make creation of a revocation certificate (and storing it in a place
31 separate from the key) mandatory.
