First you say "no, [not] at all" — it's never safe to fully discharge. Then you go on to state that problems happen "during charging" — which is a different activity. Finally you claim that a "deeply discharged battery have higher self-discharge", which at this point even my uneducated brain has to rule out as just plain illogical.
The rate at which a battery is discharged can also affect its characteristics. When you discharge a battery at a high rate (i.e., a large current is drawn quickly), its effective capacity can decrease. The reasons behind this are multi-factorial and tied to changes in chemical reactions and impacts tied to the battery's internal resistance.
But that's about it. False. Today, most batteries never truly fully discharge. What you see as 0 percent or "dead" when your phone or laptop won't power on is the battery still sitting at somewhere around a 10 percent charge. This is why, when you hold the power button, the screen will turn on long enough to tell you to charge the battery.
Full eruptions should be avoided because they put additional strain on the battery. Studies have shown that a lithium-ion battery regularly discharged to 50% before recharging will have a longer lifespan and may retain up to 1,500-2,500 cycles, compared to just 500-1,000 processes if regularly fully discharged.
No, it is not OK to have a Li-Ion deeply discharged at all. Here is why: When discharged below its safe low voltage (exact number different between manufacturers) some of the copper in the anode copper current collector (a part of the battery) can dissolve into the electrolyte.
“If a battery does become deeply discharged, special care must be taken during the subsequent recharge. With the aid of very low current, an attempt must be made to rebuild the basic voltage so that charging can then resume normally from 3 V,” says Heydecke.
Complete Guide to LiFePO4 Battery Charging & Discharging
When the LFP battery is charged, lithium ions migrate from the surface of the lithium iron phosphate crystal to the surface of the crystal. Under the action of the electric field force, it enters the electrolyte, passes through the separator, and then migrates to the surface of the graphite crystal through the electrolyte.

Is it Bad to Fully Discharge a Lithium-ion Battery
Lithium-ion battery packs should not be fully depleted and recharged frequently (deep-cycling). Utilizing only 20 or 30 percent of the battery''s capacity before recharging significantly improves battery life. Five to ten shallow discharge cycles are roughly equivalent to one full discharge cycle. 2. Avoid High Charge and Discharge Currents
