I don't really know why I thought I needed that feature but as some gateways
implement this feature (the ability to enable or disable each port), I must
have told myself I may have missed here.

On a general point of view, as most Dahdi cards have a light showing nearby
port status, it should ideally possible, to turn this light off when a port
is disabled.

But I must also add it doesn't seem very important to me to have this
implemented.

What about adding per-span section headers like Asterisk .conf files ?
[span1]
group_lines             1
pri_termtype
        SPAN/1          TE
        SPAN/2          TE

[span2]
group_lines             2
pri_termtype
        SPAN/2          TE


I don't think we need to define any further what a span is, beside that
rules that applied to the whole genconf_parameters ("no more than 1
group_lines statement") should apply to each section.
