+    This pass preloads a transform library and makes it available to a subsequent
+    transform interpreter passes. The preloading occurs into the Transform
+    dialect and thus provides very limited functionality that does not scale.

+    Warning: Only a single such pass should exist for a given MLIR context.

Why is there such a limitation? `registerLibraryModule` pushes to a `SmallVector`, so I think multiple such passes in a pipeline would be OK.
