Absolutely you should.
Apart from the existing and former team members (particularly 0brand - come back man), very few people are making regular, significant contributions.
In recent times, all templates and nearly all (non-dev) pages have been edited mercilessly, regardless of the original author. That was for reasons like:
- wiki consistency (formatting etc.)
- clarity of expression
- updated material/references
- removing duplication with existing pages/entries
- clear communication of content/procedures
- factual accuracy
- shorter sentences/paragraphs
- active versus passive language
- better sectioning
- defining unfamiliar terms
- ensuring an adequate number of references/footnotes
- citing original material/research
- removing redundant information
- shifting long text bodies into tables where possible
- inserting images to improve instructions/concepts
- cross-referencing with other Whonix entries
- updating links
- and more
A general principle of editing is that even with solid contributions by experienced authors, multiple revisions are normally required to improve it so it meets the publication standard (three rounds is often cited). That doesn’t mean all material will require editing, but the likelihood increases as the entries age or when the material is lengthy or complex.
The way I see it, other eyes on your material and proposed changes/possible improvements reinforces its value, rather than suggesting it it is somehow deficient.
