howdy after this was published (https://digiday.com/media/wtf-are-related-website-sets-in-googles-privacy-sandbox/) it raised questions for me about what is allowed under RWS, as I haven't seen specific clarifications in any documentation. If anyone were able to answer any of these or all that would be helpful:

1. Are organizations allowed to submit multiple RWS submissions? The current 5-domain cap on "associated domains" makes it impossible for normal sized publisher groups to use this feature. Is G suggesting that organizations, with lets say 25 publisher domains in their network, submit 5 unique RWS submissions and group their sites based on something? Can you clarify grouping strategies or why this is still capped at 5 even though many organizations have tried to submit pull requests with over 5 associated domains?

2) If submitting multiple RWS submissions - 5 submissions w/ 5 sites each, total 25 sites - can you reuse the same "Service Domains" across each of these submissions? My understanding was that a service domain could NOT be in multiple submissions (as this creates obvious cross domain tracking possibilities), but if that's the case, how is a publisher group supposed to use the service domains concept? Are you suggesting that if a publisher group has a service domain currently in use (like for login syncs?) they need to clone that infrastructure across multiple domains? So this example publisher group with 25 domains and 5 RWS submissions would also need 5x of each "service Domain" being used? So 5x their SSO infrastructure? And just clone those services across each domain? That sounds outrageously costly to pivot into without a bunch of red shining lights pointing this out to the industry. There are some licensing products that are domain-based, so suddenly requiring 5x licenses just to maintain your own login SSO infrastructure seems untenable or at least a big cost increase.

3. Are there any "owned & operated" restrictions for RWS submissions as seemingly alluded to @ https://github.com/WICG/first-party-sets?tab=readme-ov-file#use-cases but the opposite alluded to in the public content @ https://digiday.com/media/wtf-are-related-website-sets-in-googles-privacy-sandbox/? Will it be possible for an SSP investment group to drop their logo in the footer of websites they partially own / have invested in (with the primary purpose being to control their ads.txt/app-ads.txt and share revenue from it)(while not operating any of the stories / writing) - publisher investment schemes which are becoming increasingly popular - to list all the sites they have invested in, within 5 domain groupings in RWS? Or if the 5 domain cap is lifted, to submit all their domains they have invested in? Are there any explicit *owned & operated" frameworks to help folks navigate what is allowed now and what could get a domain removed in the future?

Thanks for any feedback on this,
