I think it would be unwise to make assumptions on how people will use this feature. They might want to ask for many more records along with A/AAAA records. If we change a core DNS feature, it should not designed for a specific DNSSD use case of HTTPS.
The extension is already limited to a maximum of 7 additional QTYPES, and some might argue that that's too many. A consideration here is the opportunity for amplification.
The main DNSSD use case is TXT+SRV. A+AAAA+HTTPS was an example of a future use case that might be popular outside of DNSSD, and where NSEC bitmaps are not efficient.
I'd also say that this is an extension - it does not change any existing core DNS features. It's 100% backwards compatible.
