To be pedantic, removing the hold is the safe option if gluing is decided against
Based on the information we have available, I disagree.
For the pedants, the “safe” in my reply was in relation to reputation of the individual (not) doing the remediation work.
If one chooses to attempt to onsight an E7 (especially on a sea cliff) then one should accept the need to assess the risks for one’s self as one is climbing. If one chooses to pre-inspect then one will identify the hold during the pre-inspection process (as has happened here).
I would very much not condone deliberately removing the hold based on the information available to us on this thread. This would certainly not be “safe” as per my meaning.
