Every magic item (even the more “common” ones) is valuable and treasured, even if it might not be used often
A +1 sword can split the hide of the toughest monsters and beasts, and is the heirloom of a powerful marquis
Three healing potions on the raised dias of the church, awaiting the arrival of the prophesied heroes, who will need them to vanquish the vampire
Or the duke with more money than sense, who has a small trove of magical items like the Stone of Gravity sensing or the Ring of Purple death detection. The twist is that in some forgotten corner of his room is a dagger that glows in the presence of demons (including the ones disguised as humans to overthrow the kingdom)
My 2 cents is that at the low levels, players need a bit of a buffer. A Lvl1 wizard with +0 CON can be one-shot by a goblin rolling a crit, to say nothing of the bugbear boss of the first encounter in Lost Mines of Phandelver (many people’s first introduction to DnD 5e)
So minor selective fudging to keep the characters alive long enough for them to at least be wealthy enough to afford a Revivify seems like a small and harmless enough concession to me
