Bedrock realms currently have the ability to invite anyone who has a realm's respective invite link. For public realms, this puts a lot less stress on the realm owner, especially if said owner is busy and does not have the time to invite people manually. I would like for java realms to have a similar feature, working similarly to how they work in bedrock, where anyone with the invite link to a particular java realm would be invited to join that realm.
As it currently stands, public java realm owners are under a lot of stress. Aside from any real life issues outside of the realm, public java realm owners have to manually log into minecraft, go to the realm page, and manually invite every single player that wants to join the respective realm. This is very time consuming, especially for bigger realms, where the owner could instead be focussing on further developing the community or focussing on real life issues outside of inviting people to the realm.
With java realm invite links, this issue would be eliminated, putting a lot less stress on public java realm owners. Furthermore, with the current push for parity between bedrock and java, adding java realm invite links would further promote parity between the two editions. Invite links would also allow for java realm owners to instead focus on developing the realm's community and to also focus on any real life issues outside of the realm.
