Extremely slow compilation when silencer plugin enabled

Next lines of code compiles at least 25 seconds when silencer plugin enabled and just 1 seconds with disabled plugin

import sttp.tapir._

case class Foo(a: Int)

object Main extends App {
  val a = implicitly[Schema[Foo]]
    .modify(_.a)(_.description("foo")) // 1s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 1s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 1s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 1s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 1s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 1s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 1s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 1s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 1s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 1s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 2s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 6s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 16s with silencer and 1s without
    .modify(_.a)(_.description("foo")) // 25s with silencer and 1s without
}

where modify - is macro function from tapir library.

I found ugly workaround: breaking method chain into two or more chains like:

val a = implicitly[Schema[Foo]]
    .modify(_.a)(_.description("foo")) 
    .modify(_.a)(_.description("foo")) 
    .modify(_.a)(_.description("foo")) 
    .modify(_.a)(_.description("foo")) 
    .modify(_.a)(_.description("foo")) 
    .modify(_.a)(_.description("foo")) 

val b = a.modify(_.a)(_.description("foo"))
    .modify(_.a)(_.description("foo")) 
    .modify(_.a)(_.description("foo")) 
    .modify(_.a)(_.description("foo")) 
    .modify(_.a)(_.description("foo")) 
    .modify(_.a)(_.description("foo")) 
    .modify(_.a)(_.description("foo")) 
    .modify(_.a)(_.description("foo"))

Ok, I’ve decided to go on and ignore macro expansions by default. I’ve also introduced an option to bring back the old behaviour (-P:silencer:searchMacroExpansions). These changes are available in freshly released 1.6.0
