Here an attempt for a workaround.
It's not tested beyond the given example, up to you ;)
\new Staff {
\override DynamicLineSpanner.after-line-breaking =
#(lambda (grob)
(let* ((staffs
(filter
(lambda (e) (grob::has-interface e 'staff-symbol-interface))
(ly:grob-array->list
(ly:grob-object (ly:grob-parent grob Y) 'elements)
(for-each
(lambda (staff) (set! (ly:grob-object grob 'staff-symbol) staff))
staffs)
;(format #t"\nstaff-padding: ~a\nY-offset: ~a\nstaff-symbol ~a\n"
; (ly:grob-property grob 'staff-padding)
; (ly:grob-property grob 'Y-offset)
; (ly:grob-object grob 'staff-symbol))
))
\override DynamicLineSpanner.staff-padding = 10
c'1\p\< c'1 c'1
\break
c'1 \stopStaff \startStaff c'1 c'1
\break
c'1 c'1 c'1
\break
c'1 c'1 c'1\f
}
\paper {
indent = 0
ragged-right = ##t
}

Isn't this still a bug? Or, rather a gap in system functionality for which
no workaround exists?
Starting a new DynamicLineSpanner creates two separate hairpins:
%%% BEGIN %%%
\version "2.19.82"
\new Staff
{
\override DynamicLineSpanner.staff-padding = 10
c'1
\p
\<
c'1
c'1
\break
c'1
\!
\stopStaff
\startStaff
c'1
\<
c'1
\break
c'1
c'1
c'1
\break
c'1
c'1
c'1
\f
}
\paper
{
indent = 0
ragged-right = ##t
system-system-spacing.minimum-distance = 30
}
%%% END %%%
[image: two-hairpins-instead-of-one.png]
... when what's needed is one single hairpin that governs the music of all
four systems.
Or am I missing something, and there is a way to generate a single
multisystem hairpin that governs all four systems?

It doesn't. It's just that the DynamicLineSpanner has a relation with
the Staff it was started in.

If you start a new DynamicLineSpanner like
c'1\!
\stopStaff
\startStaff
c'1\<
it will be properly spaced. It's probably not the only spanner
unprepared to span pieces of interrupted staff symbols.

Bug: restarting staff destroys DynamicLineSpanner.staff-padding after line break
Hi,
Restarting the staff during the lifespan of a multisystem
DynamicLineSpanner destroys the value of DynamicLineSpanner properties
(like staff-padding) that were set when the DynamicLineSpanner was created.
In the MWE below, the hairpin should exhibit staff-padding equal to 10
staff spaces below all four systems; but the value of staff-padding is lost
at the point (in system 2) that the staff is restarted; we see evidence of
this after the next line break (in systems 3 and 4) where no staff padding
appears.
%%% BEGIN %%%
\version "2.19.82"
\new Staff
{
\override DynamicLineSpanner.staff-padding = 10
c'1
\p
\<
c'1
c'1
\break
c'1
\stopStaff
\startStaff
c'1
c'1
\break
c'1
c'1
c'1
\break
c'1
c'1
c'1
\f
}
\paper
{
indent = 0
ragged-right = ##t
system-system-spacing.minimum-distance = 30
}
%%% END %%%
