ABS bleed required?

Here is the short version of my question: Does removing all four calipers by disconnecting the line that connects on the backside of hte caliper, and then leaving them off for an extended period of time, necessitate an ABS bleed (meaning having a PIWIS or PST2 ABS bleed)?

Long version: This is an '04 track-dedicated 986S. After two years of heavy track use, I started to get strange, uneven wear on my pads. During the off season (now), I decided to rebuild the calipers - replace the bore seals, dust boots, bleed screws and the pistons.

I've removed the calipers from all four wheels, and the calipers are on their way to be media blasted (going to repaint too) while I wait for the new parts to come in. I've simply let the fluid drip into buckets under each wheel.

I have not opened any ABS lines - not touched anything except disconnecting the lines in the wheel well.

Do I need to have an ABS bleed when I put this back together, or will multiple and thorough conventional bleeds (after refilling with a motive power bleeder) be adequate?

I've read other posts about changing the brake lines, and the consensus was an ABS bleed in that scenario was not needed. Wondering about this specific situation though. Thoughts?

A conventional bleeding procedure, or power bleed is sufficient if well implemented.
