[0] For example link|title would just show 'title' in the document 

[1] For example, 1 a/b/c, 2 a/b/c 

[2] That is, can make one word monospaced or include a block of plain-text information like code 

[3] That is, no shared accounts required 

[4] That is, none of the wiki is viewable without authentication 

[5] At least Edge/Firefox/Chrome/Safari 

[6] Ability to easily create sub-spaces on the wiki that have their own permissions, to support Working Group segregation 

[7] Ability to create a space, and then have sub-spaces under it inherit the same permissions (so we don't have to manage things page-by-page) 

[8] That is, users can self-provision or at least change their own passwords and update their own profiles 

[9] Option to not just link an attachment in the page, but also optionally show the contents of something like a document or spreadsheet in the page content
