Research direction
Start with the OnConfiguring example and the IMigrationsSqlGenerator replacement described in the issue, then trace how custom migration functionality reaches MigrationBuilder. No repository files or tests are named, so first identify the relevant migration service-registration and generator code. Done means the issue's proposed compositional extension model is defined and supported without requiring packages to overwrite the existing generator.

Description
Problem
I just read this article : https://docs.microsoft.com/de-de/ef/core/managing-schemas/migrations/operations
Reading the details about how to implement the generator objects for custom migration functionality it appears to me, that you can only extend migration functionality by overwriting existing one.
protected override void OnConfiguring(DbContextOptionsBuilder options)
=> options
.UseSqlServer(connectionString)
.ReplaceService<IMigrationsSqlGenerator, MyMigrationsSqlGenerator>();
Solution
If a compositional approach of this were to exist it would be possible to write many packages which extend the functionality of the MigrationBuilder, which seems like a much better alternative?
