I have a counter-proposal.  ;-)

How about adopting the use of a leading dummy character in otherwise
blank lines inside an `EX`/`EE` region?

Here's an example from sprof(1).

Before:

.EX
$ \fBcat prog.c\fP
#include <stdlib.h>

void x1(void);
void x2(void);

int
main(int argc, char *argv[])
{
    x1();
    x2();
    exit(EXIT_SUCCESS);
}
.EE

After:

.EX
$ \fBcat prog.c\fP
#include <stdlib.h>
\&
void x1(void);
void x2(void);
\&
int
main(int argc, char *argv[])
{
    x1();
    x2();
    exit(EXIT_SUCCESS);
}
.EE
