Yes. There is also a proposal for "&" tags instead of #, which will change the logic from ORing to ANDing, but it's not merged yet

Oh if I understand what you're saying, if you have multiple values in the single letter tag
```json
{
"#t": ["gm", " bloom"]
}
```
The relay should interpret that as "events with the "gm" OR "bloom" as values for the "t" tag? And this proposal using "&t" would make "events with "gm" AND "bloom"?
