I believe that this behaviour is defined by libx11
(https://gitlab.freedesktop.org/xorg/lib/libx11) and it isn't as simple
as saying that it always produces ć: it's supposed to depend on your
locale.  A grep should make the intent clear:

  <cjwatson@niejwein ~/src/freedesktop/libx11 (master=)>$ git grep 
'^<dead_acute> <c>' nls
  nls/en_US.UTF-8/Compose.pre:<dead_acute> <c>                    : "ć"   U0107 
# LATIN SMALL LETTER C WITH ACUTE
  nls/fi_FI.UTF-8/Compose.pre:<dead_acute> <c>                        :  "ć"  
U0107  #  LATIN SMALL LETTER C WITH ACUTE
  nls/iso8859-1/Compose.pre:<dead_acute> <c>                      : "\347"      
  ccedilla
  nls/iso8859-13/Compose.pre:<dead_acute> <c>                     : "\343"      
  cacute
  nls/iso8859-15/Compose.pre:<dead_acute> <c>                     : "\347"      
  ccedilla
  nls/iso8859-2/Compose.pre:<dead_acute> <c>                      : "\346"      
  cacute
  nls/pt_BR.UTF-8/Compose.pre:<dead_acute> <c>                    : "ç" 
ccedilla  # LATIN SMALL LETTER C WITH CEDILLA
  nls/pt_PT.UTF-8/Compose.pre:<dead_acute> <c>    : "ç" ccedilla # LATIN SMALL 
LETTER C WITH CEDILLA

I hope this will help you narrow down where the problem is: either the
compose definitions aren't taking effect, in which case you'd need to
track down what's supposed to be applying them and isn't, or the compose
definitions are wrong, in which case you would be best off taking this
up with X11 upstream.

(That said, while I don't use dead-key layouts myself, I seem to get ç
when I type Compose ' c even though that isn't what the Compose file
says I should get.  Not quite sure what's going on there.)

Given that this is (as far as I can tell) supposed to depend on the
locale, there should be no need to play off different groups of people
against each other like this.
