First, what is wrong with Sorcerers as written? They are already a popular choice at many tables.
They underperform mechanically. This has been a concern literally since 5E came out. My experience is that they also underperform at the table. They're not a "trap" option, nothing in 5E is, because everything in 5E is reasonably playable, but they contribute noticeably less than other similar classes, even with the same players.
They're popular because most people who want to play an arcane-type spellcaster will pick them ahead of Wizard, because D&D's idea of what a Wizard is, is a weird Vancian deal, which tends to confuse newer players and often causes distaste in people coming in from fantasy literature and other games. Powergamers will reliably pick Wizards because they're a lot stronger, of course.
