I recently got to experience the international transit facilities at DEL for myself. I arrived early in the morning on an Ethiopian Airlines flight from ADD, and had a connecting flight around 6 hours later to SIN on Air India. All on the same ticket.
ET had printed me a boarding pass for the DEL-SIN flight when I checked in at Addis Ababa, but this was not accepted at DEL. I needed to get a new boarding pass printed by Air India in Delhi.
After arriving, an ET ground staff member informed me that I would need to go to the international transfer area and wait there until the boarding time of my next flight. That was 6 hours away, so I (politely) mentioned this and that I would like to wait for my next flight in the lounge. The ET employee said she'd try to get me my new boarding pass in around an hour.
I went over to the international transfer counter. Luckily there was an Air India employee there, but she told me that I still needed to wait until they received some documentation from Ethiopian Airlines before they could print me a new boarding pass. After waiting around 1.5 hours, I went back to the desk and was told "5 more minutes". They did indeed call me over 5 minutes later, checked that I'm eligible to enter Singapore, checked my passport and baggage receipt, and then issued me a new boarding pass. From there I just had to clear security and was able to walk upstairs to the international departures area.
The Air India lounge wasn't much to write home about, but it was certainly better than the transit holding pen.
The international transfer waiting area consisted of the following amenities:
- Two rows of seats
- Nine nap chairs
- Some rubbish bins
- A phone charging station
- Three pot plants

It was also possible to leave the holding pen to access a toilet, drinking water fountain, a vending machine selling soft drinks, and a machine that spits out a wifi access code. (Said vending machine does not accept cash or foreign credit cards!)
No food of any sort was available in the holding pen.
It ended up being OK but wasn't a particularly fun experience compared to transiting in most other countries.
Air India and Vistara at least had staff at the transfer desk counters, but passengers on other airlines basically had to just wait until someone from the airline fetched them. A few people looked like they had been waiting a very long time and were over it.
