I always find it interesting to see how mathematicians understand our
proof system. It definitely influences its future evolution.

Just looking at the PDF it was obvious to me that this is an informal
(La)TeX document, the way how mathematicians like to do it.
Did you know that Isabelle is first and foremost a formal document
preparation system, with LaTeX merely as backend for low-level
typesetting? See the explanation of "isabelle mkroot -d" in the "system"
manual.
Using Isabelle sources for a document like yours makes it easy to quote
formal pieces. either checked or unchecked (e.g. via the @{text} and
@{theory_text} antiquotations). It also makes it easier to keep the
document up-to-date wrt. inevitable changes of Isabelle.
