QueryStringFilter in HTTP Protocol

[probins]

Currently, there's a dependency for this with the note "remove this dependency in 3.0". Protocol/Script has similar logic yet there's no dependency. Why does removing it have to wait for 3.0? Can we not get rid of it now? Surely, by definition, a QueryStringFilter is only required if there is a query string to filter, which in many cases with HTTP protocol there isn't..

+1 to remove this dependency; a note into notes/2.12.md is suffisant.

I'm also fine with removing the dependency. So long that we have a note in 2.12.md.

@probins: to answer the questions you pose in the description, the dependency was added when we separated logic from the HTTP protocol (see 49e96f3). Since this logic had been included in a previous 2.x release, to maintain backwards compatibility, the dependency was added. For the Script protocol, this optional functionality was added between releases, so you always only got it when you included the extra dependency explicitly.
