Tape machines in mastering rooms, why?

What is the purpose of a tape machine in a mastering room? I can only figure a couple scenarios: that they are used to bounce D/A/D for the sake of the sound and character of tape or that they're there for capturing and remastering older mixes and albums where master tapes are the truest source available.

Pretty much nailed it
I had several reels of tracks that were mastered from tape

There is also the big secret of using tape for the predelay signal for the track width on lathes.

Really? How exactly does that benefit cutting? I know this may be an involved answer, so in a nutshell is fine, but am curious.

When the signal is lower the groove is cut finer permitting more music on the side.

But how does that differ from simply reducing signal volume prior to the cut?

I gave you the nutshell answer. From

http://pure-analogue.com/de/die-bandmaschine/

Quote:
Why is the analogue delay so important now? In the early days of the record, the signal of the master tape was cut directly into the paint film. Due to the constant groove width, this resulted in only a limited play time per side. However, the groove width can be adjusted depending on the level of the signal and from the 1950s the so-called variable pitch was used when cutting paint films - so the running time of an LP could be increased by about 60%. Here, the advance of the cutting head of the cutting machine gets the information in time before the actual music signal to provide the level of the signal according to the paint film space for a reasonably wide groove available.
The music signal must therefore be delayed by exactly the time that the LP needs for half a turn. This so-called analog delay consists of two playback sound heads and a diversion over several roles and explains itself, if one looks at the course of the tape. Coming from the left-hand reel disc, the tape first reaches the first replay sound head, at which the signal for the cutting head drive is picked up. Thereafter, the tape passes over several pulleys before it reaches the second sound head for the music signal. The time required for this corresponds exactly to the time it takes for the LP to turn halfway through.

avare, I know, and that's exactly what I asked for. Couldn't help wondering further though. Thanks for the details!
