Value includes
1. Cost to run (computed from SERVER-70331)
2. BFs uniquely caught (computed via looking at Jira tags)

Paths forward include
1. Do nothing
2. Remove as required variant
3. Remove as required variant and drop down testing to daily
4. Remove as required variant and drop down testing even lower than daily

EDIT: I think we will want to replace this one with asan/ubsan variant.
EDIT 2: I think replacing this one with aubsan would be incorrect since we are not running the all feature flags version on this variant.
