| No | doesn't support (but might or might not go along with it with sufficient community support) |
| Deficient | okay with the idea, but considers it to have insufficient community support |
| Evaluating | still evaluating the idea |
| Acc. until July | it is a workable solution, provided it is activated before August 1 (and therefore BIP148-compatible) |
| Wanting | positively likes the idea, but considers it to have insufficient community support |
| Weak | better than nothing at all |
| Acceptable | it is a workable solution |
| Prefer | it is what he would choose if it was only up to him and no outside influences |
