No way to decrement an allowance without reconfiguring minter

[eztierney]

No way to decrement an allowance without reconfiguring minterThe MintController contract provides a mechanism to increment a minter's allowance that only works if the minter is active, thus preventing the accidental reactivation of inactive minters, and, as described in the inline documentation, the usage of a signed transaction to reactivate a minter. This mechanism is implemented in the incrementMinterAllowance function, which in turn calls minterManager.isMinter to perform the required check.

The contract, however, provides no analogous mechanism for decreasing a minter's allowance, meaning that this can only be achieved by “resetting” the minter through the configureMinter function.
