Will it be compatible with tsgo?

When tsgo will be released as typescript 7.0 will this project adapt to use its new api?
As I understand the new tsgo internal api will not be fully compatible with current one.

Just curious :)

My understanding is that the Compiler API will be dramatically reduced in scope. If it's possible I'll update zshy to use the new IPC based API. Otherwise I'll re-implement the existing transforms using Rolldown. The developer experience will remain substantially identical. I'll cross that bridge when necessary. :)

Given that tsgo is considered imminently close to done, can we get support under an experimental option?

So, just to confirm tried using TS v7.0.3 this morning with zshy and it doesn't work. Fails with a read error. Will paste the actual error when back on the laptop.

Here's what I'm getting:
