@Pchelolo what are your thoughts here?

Since we plan to replace the old parser with Parsoid in the not-too-far-away future, it would perhaps be best to think about how this kind of thing could work in 5that new world. I personally know very little about the inner workings of parsoid. Perhaps @SubrahamanyamVarma has some thoughts.

@SubrahamanyamVarma long time no see. It would be really interesting to hear what you think. I would expect that this is exactly what parsoid was made for:-)

I think you all meant to tag me instead of the other person. :-) Adding @cscott as well. Haven't taken a look at the ticket yet, Will do later, but for now, wanted to fix up subscribers.

We would have to introduce an extension config / api option to introduce a batching mode where Parsoid appropriately batches the requests and calls the extension to process the batch and takes care to integrate the results into the document. So, the extension would still be responsible for processing the batch, but all the boilerplate handling / admin will be removed from the extension. Presumably this would be useful for any extension that shells out / issues api requests, not just Math.

So, sourceToDom is the one-at-a-time processing case. and we would probably introduce a batchProcessToDom which would return DomDocumentFragment[].
