Would you try to write/work on a collaboratibe text document (ie Google Docs or Sheets?) by editing a paragraph/sentence that's server side rendered and hope nobody changes the paragraph mid-work because the developers insisted on SSR ?

These kinds of tools (Docs, Sheets, Figma, Linear,etc) work well because changes have little impact but conflict resolution is better avoided by users noticing that someone else is working on it and hopefully just get realtime updates.

Then again, hotel booking or similar has no need for something like that.

Then there's been middle-ground like an enterprise logistics app that had some badly YOLO'd syncing, it kinda needed some of it but there was no upfront planning and it took a time to retrofit a sane design since there was so much domain and system specifics things lurking with surprises.
