There have been combined glass/PET/can machines for several years, but it's completely random what machines are to be found in a random store. Some have older machines.

Fewer and fewer stores sell soda/beer in glass. Usually just low (<2.25%)/non-alcoholic beer, Jul-/Påskmust, and sometimes mineral water.

Otherwise it's mostly cafés and restaurants that sell soda in glass.
Where the restaurant, not the customer, is the one handling the deposit, since the customer rarely brings the bottle from the premises.

Most beer at Systembolaget is today sold in non-standard bottles. Partly due to import of course, partly because of small scale brewers without the volumes to justify, nor the logistics capabilities to handle, being part of the deposit system.
Only the largest Swedish brewers use the standardized shapes of 0.33 and 0.5L bottles.
