这是他们家的IPA，比起官方的REDUX属于条件管线的迁移，这种模型管线的似乎在“迁移”上面更加注重“风格”，而非类似REDUX万物迁移那种“单纯的迁移” ，非常希望能够支持该模块

We will support PuLID in the v0.3.0 official release.

还是十分感谢付出，但是由于工作的需求，对于flux IPA的需求比较重要，相比较换脸节点，IPA对我来说是刚需，虽然支持了REDUX，但是那个并没有IPA来的好用，我知道INSTANTX（SHAKKER-LABS）的IPA的维护并不积极，但是从实用性角度出发还是非常迫切希望支持。又或者说大佬的意思是一旦支持PuLID,IPA也等同于一并支持？

I am still very grateful for your contribution, but due to work requirements, the demand for flux IPA is more important. Compared with face-changing nodes, IPA is a necessity for me. Although REDUX is supported, it is not as usefully to use as IPA. I know that the maintenance of IPA of INSTANTX (SHAKKER-LABS) is not active, but from a practical point of view, I still hope to support it urgently.

Or does you mean that once PuLID is supported, IPA will also be supported?
