l3build clean with multiple checkconfigs

Question

I have a l3build setup where some checks require more runs than most of the other ones, so I configure checkconfigs to make a separate set of checks with a different testfiledir. A simplified example would be:

-- This is build.lua
bundle = ""
module = "mypackage"
checkruns = 2
checkconfigs = {"build","build-moreruns"}

-- This is build-moreruns.lua
checkruns = 4
testfiledir  = "testfiles-moreruns"

The issue is that, sometimes, I'd like to manually clean the generated files for the package, for which there is l3build clean. However, l3build clean only cleans the directories corresponding to build.lua, and leaves the files in testfiles-moreruns in place. The only seemingly idiomatic way to do it I found is to run l3build clean -c build-moreruns, at which point I'd start considering if just nuking the build folder would not easier. But that's not very pretty, thus this question.

I think I get why this is so, so as far as I get, this is intended. But is there a way to instruct l3build to clean all generated files in build if occasionally I want to do so? (e.g. l3build clean --all). Or to configure the clean target to include all checkconfigs?
