Dumb modems have been able to detect dial tone before dialing for many a year, but the "w" cludge seems the only way to CYA when a PSTN switch is slow to return dial tone. This shortcoming has been built in ( or not ) for many a year, and no one who has the skills ( I certainly don't ) is interested enough to correct it.
Analog PSTN interfaces will be around for a long time. It deserves some attention.
