Yet, those that favor that particular solution see no problem with that.
A lot of independent chapels are not SSPX - they're just what it says, independent, usually founded by a local group of disgusted Catholics who were unable to get indult masses but did not want to go in with the SSPX. But if they do have to do the latter, at least they know that the SSPX wouldn't force them to have the NO mass.
You seem to be missing the point here. It's about their wish to continue with the Tridentine Rite mass and, in fact, all of the pre-VatII practices, the calendar, etc. Few dioceses (if any) will guarantee them this.
