Actually not Max.
You need them when you want to get both sections and sections with alt
titles of and you want to make them produce a readable outline for the PDF
reader.

Yes, look at what you have to do when you don't have alt_title.
Using lualatex, at least, let's you add the phi as a unicode character,
which already is a great improvement wrt the status quo in pdflatex [and
now I opened Pandora's box :-) ]:
#+begin_src org
,* \(\textbackslash\texorpdfstring{\phi}{ϕ}\) wraps
#+end_src
which can be simplified to
#+begin_src org
,* \(\textbackslash{}ϕ\) wraps
#end_stc
Best, /PA
