The Madu and proficiency, can you get the best of both worlds?

[Deliverance]

So, the madu is an odd item. To a non-proficient wielder, its a spiked light shield, but to a proficient wielder, its a weapon which makes you better at fighting defensively.

For reference, here is a LINK to the madu.

My question then becomes, if I want to be a sword and board character who uses a madu as a shield, but also wants the bonuses it grants with proficiency, can it be done?

You could argue that using it as just a shield prohibits you from getting the bonuses of being proficient (at which point it apparently stops being a spiked shield and become a weapon instead), but it seems to be mostly guesswork really.

What say you the community?

The Madu is already equivalent to a light spiked shield. Just that if you're proficient with it you get access to all it's features and it's performance quality.

You get it's bonuses by using it as either a weapon or a shield since it's listed as both a weapon and a shield and both entries include the bonuses.
