Debugging multiple remote targets

Hello, I intend to debug remote multiple targets with gdb. The idea is
to have two
inferiors and then add a target to each one for simultaneous debug.
Something like:

(gdb) add-inferior
Added inferior 2

(gdb) info inferiors
  Num  Description       Executable
  2    <null>
* 1    <null>

(gdb) target remote localhost:1235
Remote debugging using localhost:1235

(gdb) inferior 2
[Switching to inferior 2 [<null>] (<noexec>)]

(gdb) target remote localhost:1236

But when I try to add the second target i get this:
A program is being debugged already.  Kill it? (y or n)

Apparently gdb does not support this. I found this wiki:
https://sourceware.org/gdb/wiki/MultiTarget

Was this work on MultiTarget gdb intended to support this kind of things?

Thank you!
