You can try to reduce using stripper, most of the maps have this classname "info_map_parameters"

Valve Wiki

And use that in the "global_filters.cfg" to apply it for all maps.

e.g.

Spoiler

PHP Code:

modify:
{
    match:
    {
        "classname" "info_map_parameters"
    }
    replace:
    {
        "MeleeWeaponDensity" "2"
    }
}

modify:
{
    match:
    {
        "classname" "info_map_parameters_versus"
    }
    replace:
    {
        "MeleeWeaponDensity" "2"
    }
}
