Legal mark-up
Si quaeris causidicum loqui, locutus est tibi
If you ask a lawyer for comments, she will give you some, whether your draft needed them or not. This is a founding crux of the anal paradox. For a mark-up proves you have read an agreement, considered its content, and justified your fee.
No text is immune from adjustment, and if your only objective is to show you've read it, slipping in a harmless for the avoidance of doubt, or a without limitation or two, is the least professionally invasive way of achieving that.
No such ornamentation is calculated to improve the elegance of the text, of course. To do that you will need to disentangle some convoluted grammar. This will be seen as enemy action, especially if your edits are not directed at some legal content, however spurious.
