There are more terms:
According to wikipedia, there are 136 GAs: https://en.wikipedia.org/wiki/Gibberellin
I suppose we may want to keep some major ones (if there are), but other terms that were not in the original list don't have annotations (see https://github.com/geneontology/go-annotation/issues/5445), so for now I will obsolete them.
GO:0045544 gibberellin 20-oxidase activity
Fixed definition from: "Catalysis of the oxidation of C-20 gibberellins to form the corresponding C-19 lactones." [PMID:7604047]
to : "Catalysis of the reaction: 2 2-oxoglutarate + gibberellin A12 (GA12) + H+ + 3 O2 = 3 CO2 + gibberellin A9 (GA9) + 2 H2O + 2 succinate. This reaction results in the oxidation of C-20 gibberellins to form the corresponding C-19 lactones, via a three-step oxidation at C-20 of the GA skeleton. Also converts GA53 to GA20. GA25 is also formed as a minor product." [PMID:32652020, PMID:7604047]

because it is an intermediate in gibberellin 20-oxidase activity GO:0045544, see PMID:32652020. No annotations, so associations in EC or in RHEA.
Another family:
MetaCyc states:
Although the exact biochemical reactions carried out by this enzyme have not been identified to date, based on comparisons with other cytochrome P450 enzymes, it is likely that NAD(P)H and O2 are involved in this reaction.
Based on the lack of understanding of the reaction and the ack of annotations, I will obsolete these as well.
