hyperref fillable forms - breaking the rules

The hyperref manual states clearly:

You must put your fields inside a Form environment (only one per file).

However,

1. I can put form fields outside of a Form and

2. I can put more than one Form in a file

and it seems to work just fine (apart from the general problem even within the rules that the font in the fillable fields seems uncontrollable). See MWE. It is not possible for me to get all my fillable bits in one place. What terrible things will befall me if I breach (1) and (2) above?

\documentclass{article}
\usepackage{hyperref}
\begin{document}

%outside a form
\TextField[name=one, width=3cm, borderwidth=0]{type here:}

%Form 1
\begin{Form}
\TextField[name=two, width=3cm, borderwidth=0]{type here:} \\

\TextField[name=three, width=3cm, borderwidth=0]{type here:} \\
\end{Form}

%And another one
\begin{Form}
\TextField[name=four, width=3cm, borderwidth=0]{type here:} \\

\TextField[name=five, width=3cm, borderwidth=0]{type here:} \\
\end{Form}
\end{document}

Why do you want to do this? Why not just use a single form? –  cfr Mar 24 at 1:33
