I would only vote for some sort of powerful "pro" dock if:
1) it's 100% optional to buy
2) it doesn't require any significant engineering work from devs, but they are free to go the extra mile if they want to, as long as it's not to the detriment of the non-pro dock version)
3) it doesn't come with a stupidly high price tag
Marketing line should be:
"Nintendo Switch 2 games are a huge step up from the original Nintendo Switch, and for those of you who want extra fidelity or other additional graphical features/options (depending on the developer), we have the Pro Dock, an optional extra, available at [insert unreasonable price]"
