There's always the question which side of a two-mod relation is responsible for implementing certain compatibility features. These days, often enough the answer seems to be: "It's the mod pack author's responsibility."
The reason why mods don't usually do that for each other is that it affects balance. IMHO the provider of the resources should make the decision whether to establish such a cross-mod relation by default, so in this particular case, M&A could define the (optional) alchemy catalyst infusion recipe for that conversion. If Botania did it, that felt like M&A design decisions are being questioned by an otherwise completely unrelated mod.
