Done, although that sounds slightly strange to my ears, but I'm not a native speaker.

One thing that makes it sound a bit strange is that the FreeBSD doc style has a rule about not using contractions (such as "ULE's").

English speakers use them all the time, English books use them all the time, and non-formal English writing (such as emails, blog posts, git commit messages, etc.) use them all the time. I even see them in some academic conference and journal papers!

So it's [sic] very understandable that when we avoid them, the language doesn't [sic] sound normal.

Contractions are to be avoided, yes. But then, a fine point of grammar (at least from my POV). Feels pretty obvious to me that 's is a contraction when replacing is ("the cat's black"). But is the possessive "'s" really considered a contraction also? Out of curiosity, contraction of what?

Sorry, my bad! You're correct, "ULE's" was ok, and it's not a contraction.

The original text was:

with current ULE's design,

which has the word "current" in the wrong place. I suggest either:

with the current ULE design [my originally proposed text]

or

with ULE's current design [which might flow better?]
